I think it's not really possible at the moment. If you want this to work
with large searches then it probably needs to be done at the CLI level
(see [1] for work in progress adding sorting by file size).

Luckily 'From' and 'Subject' are already value slots in the database,
which means that nothing should have to change in the database to add
those sort orders (i.e. it should be less work than [1]).
