Using orderBy such as player in players | orderBy: 'first_name' causes the wrong item to be dragged between two lists. It appears the ui-sortable list is based off of index, prior to sorting.

I started to create a plunker example outside of my project, but it's not quite working, so it's not very useful. I'm experiencing this issue when 2 or more lists are connected and list items are dragged between the two.

It appears to be an issue with ui.sortable indexing items prior to orderBy processing.
