Hi, @Joe Cisar Welcome to the Microsoft Q&A forum, Thanks for posting your question.
If I understand correctly you want to know if there is a way to change the default return order in CosmosDB GremlinAPI
There is not, and the return order is technically based on rid not ts, The default return order is rid, However, order by with range does not imply a scan It will only fetch the range from the backend
That does not stand in a more complex case where the ordering is not directly on the element.
If you think it is doing a full scan, connecting the execution profile may give you more insight
