Good return on mysql command line bad return in perl DBI

So I have a table which contains records that look something like this:

and so on.

When I run the following query from mysql command line it returns exactly what I want.

SELECT *, (@rownum := 0)
FROM (SELECT @rownum := @rownum+1 AS rank, team_id, team_name, points FROM teams order by points DESC) AS derived_table;

This exact same query in perl using DBI return al the data but rank is undef instead of where they would rank in points. Has anyone else had this problem? Is my approach to this problem even the right one? I am worried that this will not be efficient if I get a few million rows in teams. Am I right? Any constructive feed back would be great.
