Hmm... guess i'll give out a secret. It takes priority depending on where your pouch actually is in your inventory. If you have no platinum coins in your main inventory, a sack with coins in the first space, and a pouch with coins in the 2nd space, it will take coins from the sack. If the coins in the sack run out, supposedly it will attempt to drop other things before moving on to the next container. I haven't proven this entirely yet though.
