This line matches a non-empty digit sequence of any length, and I
thought the longest match would win. Why is that not the case here?
Frankly, I'm scratching my head over it. Any ideas?

Yes. The capture group ([.][0-9_]*) should occur once or zero times. So
this `([.][0-9_]*)?` will fix it.

Oh, good catch! That's the missing piece.
