Does this implementation work towards being able to do CREATE INDEX ... CLUSTER TABLE So that we can do both actions with just one sort of the data? I think there needs to be an option to force this to do either sorts or indexscans. On a large table you may not have the space to perform a full table sort, plus on a multi-column index we may not accurately predict the cost of an indexscan.
