Bug 31455: Make batchMod sort by order scanned

To test:
1. In batch item deletion and batch item modification add some
   barcodes.
2. Notice they are being sorted by item number, not in the order
   scanned.
3. Appply patch and restart services.
4. Try scanning items again in both batch item deletion and batch item
   modification.
5. The found barcodes should now sort by order scanned.
