I think the problem is this: with things like hash moves, good captures, killers, etc, by the time you have tried all of those, either you have already failed high, or you are never going to fail high at this position. In the so-called ALL positions, ordering is irrelevant anyway, and wasting computing resources trying to improve ordering there is pointless. At the CUT nodes, you probably get the cut before you get a chance to take advantage of your idea. So you are just adding overhead to ALL nodes, without benefiting CUT nodes at all, which is just a time penalty...
