What about `Enumerable#sort_by`?

Also note that `sort_by(&:to_s)` is actually faster in 1.9 than an expanded block (at least according to http://stackoverflow.com/a/2211760/155270), so we probably shouldn't be afraid to use it since 1.9 is our primary target. Not that it matters that much either way in this case, but if I recall back in the merb days we avoided it due to the perf penalty, which no longer is the case.
