I tried exactly the same thing. I always find WolframAlpha frustrating for anything except arithmetic. Example: search "sat scores" and you get some info about SAT scores, including a histogram by gender. Search "sat scores male" and the query is not understood, and you get the page for SAT scores. Search "sat scores of males" and the query is not understood, and you get the page for "sat male", i.e. a page describing an infant born tomorrow.
