You need a HASH+RANGE key to do sorting:
http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/QueryAndScan.html
Scans can filter on attributes that are not part of an index but can not sort. That's based on the architecture of DynamoDB:
While the scan is executed in parallel on the various partitions that hold the matching key (decided by the hash) it is impossible to sort all the results on-the-fly (it would only be possible with a locking and mutex and this wasn't desired by the design).
Create a HASH+RANGE key and it should work.

Please see 4509a7b as an example how to achieve that (assuming I get the intention right from your code)

- When 'findBy' method is annotated with @EnableScan or on class level, and the method uses only hash key (and range key), the method still executes scan instead of query. There is only a check if the used fields are GSI, but no checks if all the fields are hash/range keys. HOT 2
