I've done some research about what is the priority order in the cisco routers, regarding NSSA and regular external routes.
The problem is that it seems many IOS versions are still conforming with older RFC1587, which is obsolete now because of the RFC3101. Basically, the first one says E-routes are more preffered over N-routes, if they are of the same type and with the same metric. The second one says the opposite. :) That is why labbing up such a behavior is not the answer. Does anybody know from how, say, IOS 12.4 behaves? Or 12.4T maybe? I would not like to load every single 12.4 IOS and try this out, you can imagine that. :) If someone has the answer it will save a lot of time...
