And you do need to quote the column name in order_by also.
session.query(func.sum(X.amount).label('tot_amount')).group_by(X.date).order_by('tot_amount').limit(10)
generates code
SELECT sum(x.amount) AS tot_amount
FROM x GROUP BY x.date ORDER BY tot_amount
LIMIT 10 OFFSET 0
session.query( func.sum(x.amount).label('tot_amount'), x.id ).
filter(x.datefromdate).filter(x.datetodate).
.group_by(x.id)
.order_by('tot_amount DESC')
.limit(5)
