[Chimera-users] residue order for match/rmsd

at first I would like to thank you for Chimera, it's the best structure
viewer I am aware of!
Now to my question:
I would like to match residues in two structures, but not in the
numerical order. My expectation was that if I run "match #0:1,2,3 at CA
#1:3,2,1 at CA" I would end up with least squares fitted coordinate pairs
(#0:1, #1:3), (#0:2, #1:2) and (#0:3, #1:1).
What I get, however, is a least-squares fit of pairs
(#0:1, #1:1), (#0:2, #1:2) and (#0:1, #1:3).
Is it possible to use the order of coordinate pairs given in the command
line (e.g. pair first specified coordinate of protein 1 with first
specified coordinate of protein 2, second with second, etc.) instead of
the numerical order of the residue numbers?
I would be really glad if someone could help me out on this!
PS: I use Chimera 1.3.2577 under a 64-Bit Kubuntu. I also tried some
older (1.2.something) version which gave the same results.
