I'm not particular to the intrinsics of tablespaces, but it's possible that moving it would trigger a rewrite of the contents such that the effect would be similar to what CLUSTER would do for you - it probably just moves the files though, in which case you'd perform the CLUSTER on the new TABLESPACE and then move it back.
