Always use strict; use warnings; at the beginning of your perl code. It catches common mistakes, including the one you are making.

The problem is that Perl replaces variable names in double-quoted strings by their value (we call that "interpolation"), and @rownum happens to look like a variable name in Perl. So use single-quote strings instead: 

$sth = $dbh->prepare('Select @rownum:=@rownum+1 rank, p.* from player 
+p, (SELECT @rownum:=0) r order by score desc limit 10');
