Yes VCC on 5 and ground on 12 does seem a bit odd.
I am in the UK but I need two of them.
I'm toying with the idea of getting two from Cricklewood Electronics or
using 4028's and MPSA42's which seems like a better idea but it means
finding space for 20 transistors on the board.

I think I'd agree.
I've used the Russian K155ID1 drivers from eBay which seem to work OK
(after finding out the first Eagle library I used had the power supply pins
swapped so VCC was on pin 12 - reminded me to check new library symbols
every time now) but it's clearly been a long time, since
That didn't work either, I think I've been sold a duff one.
