It may or may not be difficult, depending on your definition of
'difficult,' but it's very easy and reproducible to get something that
can be cast to integer and compared that way.  The existence of
version-number-comparison libraries like version.pm points to the idea
that it is, in fact, difficult to compare versions in general.
