Hasan Savran shows how you can order data in Cosmos DB queries:
If you need to use multiple properties in your ORDER BY then you need to define COMPOSITE INDEXES.For example when I try to run the following query and try to order the objects by CreatedOn and Score, I end up with an error because I do not have a COMPOSITE INDEX to use with this ORDER BY.
Many parts of Cosmos DB’s SQL syntax are similar to T-SQL, but some of the underlying assumptions—such as, what you need to order data—are quite different.
