Good keywords absolutely get SERP, and IDN sites get plenty of love from search engines, but it's their stated goal to suppress rankings for "parked" sites and favor "real" sites. Nothing evil about that, it's just common sense business strategy for search engines.

Sometimes they seem to favor IDN keyword domains disproportionately, but typically don't favor them enough. The pendulum will continue to work it's way toward equilibrium in both ASCII and IDN.
