Are you just trying to total the scores in @score? Maybe something like this:

my $total = 0;
$total += $_ for @score;
print "$total\n";

Inside this for loop, each element of @score is aliased to $_, so you can just keep a running total as you loop through the array. If you need to use a C-style for loop as you have, then you'll need to dereference the array using the loop index, maybe like this:

my $total = 0;
for (my $ctr=0; $ctr<@score; $ctr++) {
    $total += $score[$ctr];
    # maybe use $ctr for some other purpose as well...
}
print "$total\n";
