Restructuring to allow the logic to reside outside the RE isn't a bad idea... but I know it's not what you want. That said, I don't think your RE is bad at all. (How offensive could it be, given what it does?)

But you can clean it up a little: 

print "match\n" if /(\d{1,3})%(?(?{$1>91}).?|(?!.?))/;

I think .? is probably better than .* and you don't need the (?: ) construct around your "yes-pattern" in the conditional.
