Agreed.
Sorry, instead of "(Despite what you'd think)" I should have said "contrary
to the rules of regular expressions"
in my post.

try entering 199 using the patterns above,
none of the 3 browsers I tried (although 2 are really mozilla though they
don't act the same) match 199
 using the first pattern [1-9]?[0-9]|1[0-9][0-9]
but all 3 matched 199
using the second pattern 1[0-9][0-9]|[1-9]?[0-9]

Same result for both IE5, Mozilla (1.7) and Firefox(0.8.0+)
Guess the tester must be what's bad 'cos it sure ought to work both ways.
