Thanks Jake,
It seems we're still looking for the perfect all-around solution.
For each of these, I was looking for:
1. Does it work with a simple-tap interaction?
2. Could it work with a simple-tap interaction with some reasonable adjustment?

This goes into a keyboard up/down mode, so:
1. No.
2. Perhaps, if it worked by selecting an item and then swapped with the next one you tapped, but that would need instructions or something? Otherwise I think a completely different approach would be needed.

Same as above.

1. No.
2. Possibly, if you tap the object to select, and tap the place where it should drop.

1. Yes, but only for moving between columns, not for ordering with a column.
2. Possibly, by swapping between items, as above.
> There are plenty more.
Any which work with a tap approach as well?
