Thanks for all the replies. Here is the code that I have but still prints out the hashes unsorted? Not sure why? 
  foreach my $file ( $fns ) {
            open(FH, $file) or die "Can't open '$file': $!";
            binmode(FH);
            my $hash = Digest::MD5->new->addfile(*FH)->hexdigest;
            $file_hashes{$hash} = $file;
        }
        foreach my $hash ( sort {$file_hashes{$a} cmp $file_hashes{$b}
+}
            keys %file_hashes ) {
            print "$hash $file_hashes{$hash}\n";
        }
    }
