Have a look at Sort::Versions - a perl 5 module for sorting of revision-like numbers, too. 

#!/usr/bin/perl
use strict;
use warnings;

use Sort::Versions;
# exports versions and versioncmp

my @version_numbers = qw(
        1.1
        1.1.1
        1.2.1
        1.2
        1.4
        1.6.1
        1.6
        0.9
        1.1.a
        1.1.b
        1.3
        1.5.1
        1.5
        2.3.5-0022
        2.3.5-0041
        2.1.4.0046
);

my @sorted = sort versioncmp @version_numbers;

print join("\n", @sorted), "\n";

Running above code yields 

0.9
1.1
1.1.1
1.1.a
1.1.b
1.2
1.2.1
1.3
1.4
1.5
1.5.1
1.6
1.6.1
2.1.4.0046
2.3.5-0022
2.3.5-0041
