My advise is a completely different direction.  Don't use the arch as a node property.  There is already a node attribute called "arch" that you can use for this.

If you look at 'pbsnodes -a', you'll arch=i686 and arch=x86_64 associated with
the different nodes.  Then just add that arch to your resource request.

In general, if you've compiled and installed software correctly, 32bit binaries
run correctly on 64bit hosts.  This means that users of 32bit binaries can
simply omit the arch because their jobs run everywhere.  Users of 64bit
binaries add "arch=x86_64" to their request and it will only run on 64bit
