I think you need to treat it as a version.pm bug. The comparisons don't
match perl's.
$ perl -e 'BEGIN{package foo; $VERSION=v0.2.1_1; $INC{"foo.pm"}=1;}
use foo v0.2.20;'
foo v0.2.20 required--this is only v0.2.11 at -e line 1.

Preserving the original text for later stringification is fine.
Treating the _ as a tuple delimiter is incorrect.

If it doesn't give the same result as perl's module loading, this will
break somewhere.
