Nice solution, but I feel it would be beautiful if one's function has only one return, instead of two or more.
Using a flag as choroba stated. something like thus: 

  ...
   sub check {
    my $seen = 0;
    for my $el (@{shift(@_)}) {
        if ($el eq '3'){ # we only need the first occurrence
            $seen = 1;
            last;
        }
    }
    return $seen == 1? 'Found': 'Not Found'; # NOTE
   }
   ...
