Is there any guarantee about the ordering of contours returned by FindContours()?

The result are 'almost' ordered by image row of the first point - except for a few percent which aren't !
Is this a bug, is the ordering a weak side effect of the algorithm or are they ordered by some other criteria?

There is no order but how it is processed it is as you said nearly ordered. I suggest not to rely on it at all!
