Issue Summary

When creating a filter for a Team Managed Project with multiple tickets (that return multiple page results) and sorting by status some of the statuses are not grouped together as expected. This has also been reproduced on projects with single-page results. 

Steps to Reproduce

1. Go to Filters ... Advanced Issue Sort
2. Specify the project 
3. Specify the issue type
4. Press the "Search" button
5. Click on the "Status" header to sort

Shortcut: these actions have produced the following JQL:
project = PROJECTNAME AND issuetype = "ISSUETYPE" ORDER BY status DESC

Expected Results

All items of a given status are grouped together in the results set, across all pages

Actual Results

Some results are grouped as expected, but a few pages in the sort becomes inconsistent.

Workaround

Through the user interface (UI) by doing the following in the Status screen:

1. Access the Statuses page of your instance: https://YOUR-INSTANCE.atlassian.net/secure/admin/ViewStatuses.jspa
2. Click on any of the up/down arrows to rearrange the order of the statuses

Despite not showing on the screen, Team-Managed statuses are also reindexed during this action and it adds a sequence to the flow, this ultimately corrects the issue.
