RFC 7766 is about DNS/TCP not about DNS/HTTP, the order of processing has to be determined by the wrapping protocol. You would get it for free if this draft was about TCP over HTTP or HTTP over DNS/TCP, but it's not.
It's hard to believe we're reading the same draft. The one I'm reading is about wrapping DNS wire format requests in http, with a header saying whether it's wrapping UDP format or TCP format. (My preference is to lose the UDP and only wrap TCP, but that's a nit.)
So it's DNS in TCP in http. Since DNS in TCP handles multiple requests and out of order responses, so does this.
