No, I can't think of any way to specify the ring as a whole but with a stereotyped ordering of atoms.
As far as I know, you would either have to specify the atoms individually (such as by name) in order in the command, or "pick" them in the Chimera window one by one, first all of the atoms of interest from one molecule and then from the other in the corresponding order, then specify your ordered selection in the command with the word "sel" or "selected" or "picked"
Atom name approach, example commands:
match #1 at o1,n3,n4,c10,c9,c8,c7,c12,c11 #0 at o1,n1,n2,c3,c2,c1,c6,c5,c4
(The last command, match, should be all one line... the mail program may break it up. Also you might be using the rmsd command instead of match.)
