Have you tried kCFStreamNetworkServiceType?
Last I checked this translated to the SOL_SOCKET / SO_TRAFFIC_CLASS socket option, which is in Darwin but not in the public SDK, but the CFSocketStream values are public API.
Of course, for these to be effective the Wi-Fi driver much honour them. I don't know which, if any, of our Mac OS X Wi-Fi drivers do. Which brings us back to Terry's suggestion of using a trace to verify what's happening on the wire.
Share and Enjoy
