jquery - Setting z-index on draggable elements

I am trying to set the z-index on draggable elements using jQuery. You can see what I am talking about and what I have so far here:

http://jsfiddle.net/sushik/LQ4JT/1/

It is very primitive and there are problems with it. Any ideas on how I would make the last clicked element have the highest z-index and rather than resetting all of the rest to a base z-index, have them step, so the 2nd to last clicked has the second highest z-index, etc..

Another problem I am having with it is that it only works on a full click event but the draggable functionality works by clicking and holding down. How could I have the class applied on that initial click down and not wait for the event of releasing the click?

All you need to do is use draggable({stack: "div"}) Now when you drag a div it will automatically come to the top.

Check working example at http://jsfiddle.net/LQ4JT/8/
