Hi Thomas,
	I think the answer is no, using only normal Chimera commands.  However a simple Python script can do it, and such a script can be executed with the "runscript" command.  I have attached a script that takes a model number and a residue index as arguments and selects the corresponding residue.  If you put the script in your home directory then "runscript ~/selres.py 0 12" would select the 13th residue (input order) in model 0.
