There is a CPAN module for everything...

use Sort::Versions;

my $min = '2.0.0.0';
my $max = '3.0.0.0';
my @list = qw( 1.0.0.0 1.1.10.1 2.0.0.0 2.1.0.0 10.6.1.0 );

for my $entry ( @list ) {
    next if versioncmp( $entry, $min ) < 0
         or versioncmp( $entry, $max ) > 0;

    print "$entry is between $min and $max\n";
}
