Help to fix jquery sortable for ordered list

Please see the demo here http://trainee4.afixiindia.com/pratap/ui/shopping_cart.html

When I click on the number and try to drag for sortable,its not happening.But when I drag the li ,its working

"It mayn't be done with an ordered list because the numbers aren't represented in HTML. I have to use an unstyled开发者_运维知识库, unordered list and manage the numbers myself.":-Its a solution I think

Is there any solution.?

Just add this to your #cart ol style:

list-style-position: inside;
