Geeze, I feel weird answering my own questions.

I labbed out the FTP port scenario and these are the absolute results:

access-list 110 permit tcp host 172.24.24.10 gt 1023 10.1.1.0 0.0.0.255
eq 21
access-list 110 permit tcp host 172.24.24.10 gt 1023 10.1.1.0 0.0.0.255
eq 20

The source port is what is randomizes like anything else. These were
captured
during a data trasfer and that is the only time the port 20 session was
established.

Many FTP apps offer a knob on FTP passive mode ??
