Ha, we had the same sort of thing happen when we migrated from UW-IMAP to 
Cyrus.  :)  But, everything worked normally after the migration.  New 
messages were correctly sorted by arrival time.

Since you run Cyrus, maybe you can turn on the telemetry log for this 
particular person and see the exact IMAP protocol command that happens 
here?  From what I can see in the IMP code, it does:

   $sorted = imap_sort($imp['stream'], $prefs->getValue('sortby'),
                       $prefs->getValue('sortdir'), SE_UID);

So unless the sortby preference is wonky somehow, it should be using 
arrival date...
