Here's the subroutine that's doing all the work.

sub genes {
my ($text, $score, @genes)=@_;
my $genestr="";
my $count=0;
my $total=0;

foreach my $gene (@genes) {
    $count++ while $text =~ /$gene/g; # Count number of instances
    if ($count) {$genestr.="$gene ";}
    $total+=$count*$score;
    $count=0;
    }
return $total, $genestr;
}
