IMO it makes sense. 6.6302 and 6.63_02 are not the same thing. One is
stable, one is alpha. One is version 6.6302, one is 6.63 alpha 2. The alpha
version should always be less than an "equivalent" stable version.
What's really going on is this:
6.63_02 => 6.63_2
6.6302 => 6.6302.0
And 6.63 < 6.6302.
I know this gets in the way because people like to collapse alpha version
numbers to avoid a warning when they're compared as numbers. Ironically the
very thing people do which trips up version.pm is unnecessary with version.pm.
