Sort keys are how you get DynamoDB to return the results in sorted order. Query flexibility is one of the trade-offs to get extreme speed and size. You can always sort at the application layer but then you may be doing table scans to get the whole data set. See: Using Sort Keys to Organize Data in Amazon DynamoDB.
