It might be less work to just implement your own sorting code. I’ve found them pretty easy to implement. A bubble sort is very simple, but inefficient for a large number of items to sort. If you have a lot of cards, you would want to use a more efficient algorithm. Check out the link below if you are interested.

Good luck,

Give each card a custom property, call it "SortValue" or some such.2. *Before* the first sort: Go thru each card and set the SortValue of each card to an integer, incrementing the number by 1 with each new card.3. *After* the first sort: Do a new sort, by the SortValue of each card. This should get the former order of the cards back.
