Just tried your query and got perfect results in Google, right at the top. And I'm yet to see how WA answers that question. I think it may be able to answer it, but only if it was designed to understand this particular kind of questions and if particular pieces of information were selected for inclusion in WA's database.

WA, to my understanding is not entirely self-regulating like the Google/Web bundle and thus it will be difficult for WA to catch up. We'll see.
