I've only ever seen them called "12" and "11" for the top and next rows respectively. For example, the card code listing on the IBM 360 "green card" shows them that way (e.g., A is 12-1).
Same here. But it's not outside the range of possibility that *someone* called them X and Y, although I don't know who did. Doug Jones doesn't mention it.
Let's not forget the System/3 96-column cards. BA8421 (sort of like 7-track mag tape), with a really wacky way to combine the columns to make 8-bit bytes.
Univac, of course, had their own system with their double-45 column system, round holes and all.
