Hibernate mapping sort / order-by?

What should I use (sort or order-by) if I need to fetch a Set(one-to-many mapping)? How is sort different from order-by?

Thanks,
Vijay

from hibernate doc:

sort="unsorted|natural|comparatorClass"
order-by="column_name asc|desc"

order by is SQL order by, performed in DB
sort is in memory sorting based on natural order or trough a comparator class.
