Create a clustered index on the attribute you want it ordered by. (I'm
not sure is a clustered index can be a composite, but the docs or
someone else here will let you know :-)

Note that any inserts (or updates on the attr with the clustered index)
will cause the ordering to be broken, in which case you'll need to
re-cluster.
