Oh, whatever. I give up.
$ perl5.8.8 -e 'BEGIN{package foo; $VERSION=v0.2.1_1;
$INC{"foo.pm"}=1;} use foo v0.2.10; print "yipeee!\n"'
yipeee!
$ perlv5.10.0 -e 'BEGIN{package foo; $VERSION=v0.2.1_1;
$INC{"foo.pm"}=1;} use foo v0.2.10; print "yipeee!\n"'
foo version v0.2.10 required--this is only version v0.2.1_1 at -e line 2.
BEGIN failed--compilation aborted at -e line 2.
So, a release following an alpha version must increment the middle tuple,
and the part after the rightmost dot (which is one or two tuples
depending on whether the year is even or odd) should be like 99_01. Any
less-careful navigation of this snakepit will get you bitten.
