You can't do ranges in regexen like that, it just sets up a character class containing 0, 1, 2 and 2. You could set up both ranges in arrays outside the regex and then use the pipe '|' alternation metacharacter.

use strict;
use warnings;

my @toTest = qw{
   X-1Y40
   X13Y39
   X20Y60
   X22Y35
   };

my $rxValid = do
   {
       local $" = q{|};
       my @xRange = ( 0 .. 22 );
       my @yRange = ( 35 .. 50 );
       qr{(?x) ^ X (?:@xRange) Y (?:@yRange) $};
   };

foreach my $test ( @toTest )
{
    print
       qq{$test: },
       $test =~ $rxValid
       ?  qq{valid\n}
       :  qq{invalid\n};
}

This produces the following.

X-1Y40: invalid
X13Y39: valid
X20Y60: invalid
X22Y35: valid

I hope this is helpful.
