PoPToP 1.1.1 includes a rewrite of the GRE code which gives a more
complete diagnostic for out-of-order packets.  You might try that, to
see if the problem really is packet reordering or if it is some kind
of data corruption.  (If the sequence numbers are close together but
scrambled, then there is a reordering problem.  If the sequence
numbers are all over the map, then they are being corrupted.)

This probably won't solve your problem, but at least it would narrow
it down.
