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.
It's reminiscent of the old text adventures, where the easy part was figuring out what to do, and the hard part was figuring out the right syntax to match the coder's expectations.
