Or slightly more compactly (using trinary math instead of the trinary operator): 
(abs($a - $b) <=> $max_spread) * ($b <=> $a)

where $max_spread is the maximum range you expect your numbers to cover before wrapping. 50_000 might be a better choice than 200.

    The 200 was based upon the fact that he's showing 200 messages.

    (or maybe less than half?)
