I liked @Reigel's (accepted) answer but needed to improve it for use in one of my projects. In the code below, I introduce a new function "findClickedOption" that accounts for the fact that maybe a user will re-click an already-selected option. This still doesn't account for CTRL-clicking multiple options but is good enough for me.

    var multiselect_s=$('#ms2side__sx');
    var options_s =multiselect_s.find('option:selected');
    multiselect_s.live('click',function(){
      var clickedOption =findClickedOption($(this), options_s);
      options_s = $(this).find('option:selected');
      doSomething(clickedOption);//call your own function here
    });

    function findClickedOption(selectbox, optionsArr){
      var selectedOptions=selectbox.find('option:selected');
      if(selectedOptions.size>1){
        return selectedOptions.not(optionsArr);        
      }else{
        return selectedOptions;
      }
    }
