Search results aren't ordered chronologically

I just did a search by typing in the "Search" bar, and here's what I saw

That seems wrong: note the timestamps, in order from the top down, read

- Today at 5:13 AM

- Today at 5:16 AM

- Today at 5:20 AM

- Today at 5:06 AM

- Today at 5:12 AM

I'd naively assumed that the results would be shown sorted by time; since they're not, I do not trust anything about these results.
