if (top.location!= self.location) {
   top.location = self.location.href;
}

That will generally work, but there is a small chance of failure in the case that window is overridden. Here's a couple of clever alternatives from Nathan Smith:

<script>

// Break out of an iframe, if someone shoves your site
// into one of those silly top-bar URL shortener things.
//
// Passing `this` and re-aliasing as `window` ensures
// that the window object hasn't been overwritten.
//
// Example:
//   var window = 'haha, punked!';
//
// Note: Probably unnecessary, but just for kicks.

(function(window) {
  if (window.location !== window.top.location) {
    window.top.location = window.location;
  }
})(this);

</script>

<script>

// A more cryptic one-liner, to awe & impress.
//
// No need to protect `window` since `this` is
// immutable, and at the topmost level means
// `window` anyways. Here, we compare locations
// on the left side of the "&&" and execute the
// code in parenthesis if that condition is
// true (top location isn't iframe location).
//
// Otherwise, nothing happens. It's basically an
// if statement without wrapping curly brackets.
//
// Weird, I know. But pretty cool, right? :)

this.top.location !== this.location && (this.top.location = this.location);

</script>

Some of these services already (smartly) provide their scripts in an async fashion, this just combines them into more efficient, organized, and understandable code.

(function(doc, script) {
  var js, 
      fjs = doc.getElementsByTagName(script)[0],
      frag = doc.createDocumentFragment(),
      add = function(url, id) {
          if (doc.getElementById(id)) {return;}
          js = doc.createElement(script);
          js.src = url;
          id && (js.id = id);
          frag.appendChild( js );
      };
      
    // Google+ button
    add('http://apis.google.com/js/plusone.js');
    // Facebook SDK
    add('//connect.facebook.net/en_US/all.js#xfbml=1&appId=200103733347528', 'facebook-jssdk');
    // Twitter SDK
    add('//platform.twitter.com/widgets.js');

    fjs.parentNode.insertBefore(frag, fjs);
}(document, 'script'));

I found it going through some site code and I forget exactly who originally did it but it seems like a Nicolas Gallagher or Mathias Bynes kind of thing. Correct me if I'm wrong.

You'll need the HTML in place for the scripts to put their stuff:

<a href="https://twitter.com/share" class="twitter-share-button" data-count="horizontal">Tweet</a>

<div class="g-plusone" data-size="medium" data-count="true"></div>

<div id="fb-root"></div>
<div class="fb-like" data-send="false" data-layout="button_count" data-width="1" data-show-faces="false" data-action="recommend"></div>

var Loader = function () { }
Loader.prototype = {
    require: function (scripts, callback) {
        this.loadCount      = 0;
        this.totalRequired  = scripts.length;
        this.callback       = callback;

        for (var i = 0; i < scripts.length; i++) {
            this.writeScript(scripts[i]);
        }
    },
    loaded: function (evt) {
        this.loadCount++;

        if (this.loadCount == this.totalRequired && typeof this.callback == 'function') this.callback.call();
    },
    writeScript: function (src) {
        var self = this;
        var s = document.createElement('script');
        s.type = "text/javascript";
        s.async = true;
        s.src = src;
        s.addEventListener('load', function (e) { self.loaded(e); }, false);
        var head = document.getElementsByTagName('head')[0];
        head.appendChild(s);
    }
}

Usage

var l = new Loader();
l.require([
    "example-script-1.js",
    "example-script-2.js"], 
    function() {
        // Callback
        console.log('All Scripts Loaded');
    });
