Yes, the man page does describe and some of my attempts used it (the comma separated list, not the range). The specific results were:

ipfw3 add 101 set 1 allow tcp to 1.2.3.4 22,80
ipfw3: bad command `22,80'

That one's just invalid.

ipfw3 add 100 set 1 allow tcp to 1.2.3.4 dst-port 22,80
ipfw3 list 100                                
00100  allow tcp to 1.2.3.4 dst-port 22

It added the first port, not the second.
