I resolve it myself. Add, please, code to repository:

  <script type="text/javascript">
    (function(){
      var reverseOrder = <%= User.current.wants_comments_in_reverse_order? %>,
        historyElement = $('history'),
        updateElement = $('update');

      if (reverseOrder && historyElement) {
        // Add br-element at bottom of update for to simulate some margin from journals
          updateElement.insert({ bottom: new Element('br') });

        // Inject before journals
        historyElement.insert({ before: updateElement });
      }
    })();
  </script>

Here it code update.

  <script type="text/javascript">
    (function(){
      var reverseOrder = <%= User.current.wants_comments_in_reverse_order? %>,
        historyElement = $('history'),
        updateElement = $('update');

      if (reverseOrder && historyElement) {
        // Add br-element at bottom of update for to simulate some margin from journals
        // and apply css-clear-property to break some long commit lists
          updateElement.insert({ bottom: new Element('br') }).setStyle({ clear: 'both' });

        // Inject before journals
        historyElement.insert({ before: updateElement });
      }
    })();
  </script>

Actually, yes. I just don't know Ruby syntax, that's why I used JS.
