Any idea what is going wrong?
I'd say it's apparent that the SQL expression parser employed by DBD::CSV is unable to deal with such a complicated expression (either at all, or with the amount of type information at its disposal). Specifically, the parser expects a variable or a numeric literal as the argument to an aggregate function.

Assuming that's not the case, have you tried more parentheses ? some form of value coercion ?
