Incorrect sorting by VVM status on Fulfill Order screen

As per the primary sort for lots is by VVM status and then by expiry date. Stage 2 lots should appear before Stage 1 or undefined lots. This does not seem to be the case, and No stage + No expiry date lots appear before stage 2 lots.

Repro steps:
1. Log in as divo1
2. Start physical inventory for EPI program
3. For MRK-ROTA-1-1234 product and lot ROTAM2017B select VVM status stage 2
4. Go to order fulfillment screen
5. Start fulfillment for any order
6. Notice the no VVM status + no expiry date goes first for MRK-ROTA-1-1234

Open questions:
Is it expected that No VVM + No expiry date goes first? If so, needs to be rewritten.

Update:

Stage1 VVM Status and No VVM Status should be treated as the same in a sort order, so a lot with a smaller available Stock on Hand should come first. However, a lot with VVM Stage 1 status comes before a lot with no VVM Status when expiry dates are the same, even if it's Stock on Hand is higher.

Expected state according to the test:

• Primary Sort is by VVM Status. Lots with VVM status 2 sort first ahead of VVM status 1 or n/a. (N/a = No associated VVM status.) Within the VVM status 1 or n/a, system sorts by the next sort criteria below, Expiry date.

• Secondary Sort is by the following fields:

1. Expiry date - recommend products/lots with an earlier expiry date (nearest expiry lots come first);

2. Close out a product/lot - recommend products/lots with a smaller quantity remaining, to close out a product/lot.
