Maybe it's just too late for me to think clearly, but why are you using the ternary expression instead of an if/else? It's nice to assign a value, but you're not.

Also - and this is a guess based on the odd indenting - did you intend that the while loop and following two statements be executed when $key eq "year"?

Try it this way:

$results->bind('<ButtonRelease-1>'=>
          sub{
              $list = $results->curselection;
              if ($key eq "year") {
                &show($bros->{$data}->[$list])
              } else { 
                $index = 0;
                while($bros->{$ydx[$list]}->[$index]->{$key} !~ /$data
+/i){
                  $index++;
                }
                $yr = $ydx[$list];
                &show($bros->{$ydx[$list]}->[$index]);
             });
