I meant we can treat leading zeros as decreasing factor.
So, x.001 < x.002 < x.01 < x.02 < x.1 < x.2 < x.10 < x.20
In other words - zeros never can dropped except there are only zeros in 
the number i.e. X = X.0 = X.00 = X.000 etc.

We can look on a version number part with leading zeros as on a number 
with an implicit dot: 001 -> 0.01, 02 -> 0.2 etc. So comparing will not 
be a problem.
