title: Column Ordering in Bootstrap3 not working as expected
body: <p>I was doing some experiments with column ordering in Bootstrap 3 and came across this problem.</p>
  
  <p>How can I achieve the following order:</p>
  
  <ul>
  <li>XS: 123</li>
  <li>SM: 231</li>
  <li>MD: 312</li>
  <li>LG: 123</li>
  </ul>
  
  <p>This is what I have: <code>LG</code> doesnt work and displays <code>&lt;blank&gt;13</code> instead of <code>123</code></p>
  
  <pre><code>&lt;div class="row"&gt;
     &lt;div class="col-xs-4 col-sm-push-8 col-md-push-4 col-lg-pull-0"&gt;1&lt;/div&gt;
     &lt;div class="col-xs-4 col-sm-pull-4 col-md-push-4 col-lg-pull-0"&gt;2&lt;/div&gt;
     &lt;div class="col-xs-4 col-sm-pull-4 col-md-pull-8 col-lg-pull-0"&gt;3&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
