Found the spec after some searching. And can't say i could find anything
where it seemed to define any order on decode. I suspect the solution is to
detect the problem when the second field (that is supposed to be first)
shows up.

>From what i can tell in the code, it already tries to check the frame_num
for complementary field pairs. (only if the current one is a reference
field) I wonder why it doesn't itself there.
