Priority tags not sorting

### What Happened?

Hoping this isn't a duplicate, I'm not Git-savvy enough to properly search issues.

At some point, adding /a /b /c to items no longer sorts them by priority like it used to. The ones I've seen this on are /later tasks, but I've tried switching to /now and just making them normal bullet pointed items, no change.

### Reproduce the Bug

1. Create a list of 3 items, tasks, etc
2. Type /a on the final one
3. Type /b on the middle one
4. Type /c on the first one
5. Items do not reorder
6. Refresh page by going to whiteboards or something, then back to journal
7. No change
8. Close app, reopen, sync
9. No change

### Expected Behavior

In the past, I've been able to use /a /b /c to help order tasks within the NOW or LATER classification. Assigning /a to a task would put it above all others, leaving it without a classification would put it below C.

Start by reproducing the ordering issue in the journal with NOW or LATER items, using the /a, /b, and /c steps described. Trace the priority-sorting entry point for journal items and verify the behavior after refresh and restart. Done means items order from /a to /c, with unclassified items below /c.
