I'm not sure what you are trying to do here, but it seems that an order by
statement should at least contain something that is part of the resultrow.
"case when 5=5 then 2 else 3 end desc limit 5" does not contain any column
to sort on. So I think it will evaluate to some constant value and not
sorting is really done
