Z3 score had moved left one character compared to earlier Ozmoo releases, probably by accident, because the code did clc:sbc #15 instead of sec:sbc #15. If this wasn't an accident, it would probably be clearer to use sec:sbc #16 just to be more conventional.
Z3 time didn't respect s_screen_width so wouldn't look right in 80 column modes. I don't know if there are any Z3 time games though; I haven't been able to test this change. (I spotted this problem while merging the 5.3 changes into my Acorn port.)
