You probably would want to do something like the following: 
my $grade = <STDIN>;

my %scores = (
        "90" => "A",
        "80" => "B",
        "70" => "C",
        "60" => "D",
        "50" => "F");

my $letter_score = $scores{$grade};
if ($letter_score eq "A"){
 #return this
}

There is really no need to loop to lookup key/value pairs. I hope this helps. If you're trying to execute statements you may want to look into the eval function.
s;;5776?12321=10609$d=9409:12100$xx;;s;(\d*);push @_,$1;eg;map{print chr(sqrt($_))."\n"} @_;
