I may be missing something, but isn't this kinda like (untested!): 
sub lcs {
    my ($string, $find) = @_;

    my $l = length $find;
    while ( $l > 0 ) {
        my $pos = index( $string, $find );
        if ( $pos > -1 ) {
            return ( $pos, $l );
        }

        $l--;
        chop $find;
    }

    return;
}

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
