Bulk adding nodes to an existing queue resets sorting

It sounds like a potentially serious issue, but I'm afraid I could not reproduce it. I know it's late asking, but can you provide more info about your set-up? Are you using smartqueues? When you say "resetted", reset how? Are you using any other modules that may affect how nodes are sorted, such as Draggable Views?

Steps I took:

1. Installed a fresh version of Drupal
2. Downloaded and enabled nodequeue, views_bulk_operations, views_ui (plus dependencies views, entity, ctools)
3. Created 5 Article nodes (node/add/article) - Article 1, Article 2, Article 3, Article 4, Article 5
4. Created 2 simple queues named 'Source queue' and 'Destination queue' (Queue size: 5, Type: Article)
5. To Source queue, added the fourth and fifth articles (4, 5)
6. To Destination queue, added the first three article nodes to the queue, in order (1, 2, 3); saved queue.
7. In Destination queue, moved Article 3 to the top of the list; saved queue.

Destination queue at nodequeue/2 looks like this:

- Article 3
- Article 1
- Article 2

8. Added "Bulk operations: Content" field to Source queue view (Selected bulk operations: Add to nodequeues); saved view.
9. Navigated to Source queue at nodequeue/2.
10. Selected checkboxes next to Article 4 and Article 5; executed bulk operation "Add to nodequeues".

Destination queue at nodequeue/2 looks like this:

- Article 3
- Article 1
- Article 2
- Article 4
- Article 5

11. Reverted both queues to their original state.
12. In the Source queue view, opened the settings for field "Bulk operations: Content" and selected "Enqueue the operation instead of executing it directly" under "Selected bulk operations"; saved view.
13. Repeated steps 9-10, then ran cron.

Articles still appear in the correct order.

Drupal 7.34, nodequeue 7.x-2.0-beta1, views 7.x-3.8, views_bulk_operations 7.x-3.2, ctools 7.x-1.5, entity 7.x-1.5

If this issue still effects anyone, please reopen and describe how to reproduce.
