Here's my solution. Is this the kind of thing you had in mind?

#! /usr/bin/perl
 
use strict;
use warnings;
 
my @left;
my @right;
 
for (my $i = 0; $i <= 11; $i++) {
 
    my $j = $i+1;
 
    $j = 0 if $j == 12;
 
    print "Weigh Balls $i and $j\n";
 
    print "Enter a result for each ball as follows:\n";
    print "     b-b     Both balls balance\n";
    print "     u-d     Left side up, right side down\n";
    print "     d-u     Left side down, right side up\n";
 
    chomp( my $input = <STDIN>);
    my @results = split/-/, $input;
 
    $left[$i] = $results[0];
    $right[$j] = $results[1];
 
}
 
for (my $i = 0; $i <= 11; $i++) {
 
    if (( $left[$i] eq  "b") ||
        ( $right[$i] eq "b")) {
 
        print "Ball $i is normal\n\n";
 
    } elsif (( $left[$i] eq "d" ) &&
             ( $right[$i] eq "d")) {
 
             print "Ball $i is Heavy!\n\n"
 
    } elsif (( $left[$i] eq "u" ) &&
             ( $right[$i] eq "u" )) {
 
             print "Ball $i is Light!\n\n";
 
    } else {
 
             print "Something is FUBAR somewhere!\n";
 
    }
 
}

I haven't included any error checking for input errors, etc. It's just the bare logic.
