Have you tried adding two more fields to your array? when an item has been moved in whatever direction, you simply put a marker in the slot. As an example
Dimension achoices[x*4], aselected[x*4]

** if item is moved from left to right - from achoices to aselected
aselected[i,3] = '*'

** if item is moved from right to left
achoices[i,4] = '*'

if item has both 'slots' marked then it went from one side to the other

It's just a thought
