Maybe I could do "-p 80 --top-ports 11-20" if I knew port 80 was open.
However I guess port 80 might accidentally be scanned last in which
case it does not help.

There's special logic that cheats and puts common ports like 80 at the
front of the list (random_port_cheat in portlist.cc). But unfortunately
it still won't work because you can't use -p and --top-ports together.
(I think you should be able to, and it should take the union.)
