In an attempt to try and answer you question and try clarifying as opposed to 
making more opaque (and I'm sure Jared or someone else will correct me if my 
understanding is incorrect)

The _12345. should be matched because

a) it is more specific of a match (matches more strict characters)

b) you have a . and not a ! -- my understanding is:  . means to match 1 or more 
characters, and ! means to match 0 or more characters.

Ooooo.... that's a good one I've never used.

My guess is that _123. would be matched in that case because the first character 
is more "specific" than the X pattern match character.
