String comparison doesn't work on version numbers.

Sorry, I have trouble remembering which operator in perl is numeric
and which is string based.
Given this clarification, I assert that CPAN is really broken because
version numbers aren't floating point numbers. Indeed, how would
"2.2.1" compare with "2.2.2"? It is illogical to have multiple
decimal points in a float literal, though perl silently ignores that.
In fact, trying it out for myself, neither is less than the other!
