You can define the sort to use whatever order you want, since you pass 
the comparison function that the sort will use.  So you can define your 
sort order to use something besides the index, perhaps the item's data 
value.  Then just change that value when you want to change the order, 
and then resort the listctrl.

BTW, what is wrong with the default behavior of the move up and move 
down buttons?
