Ok, the upper o-ring is the smaller one of the two, it looks about the same nominal inner diameter size as the thick one between the head and scrubber.Mine came with the bigger thin one at the top and the smaller thin one below. The thicker smaller one seals the scrubber.
So from top to bottom, they are in this order:
The smaller thin one - it seems like it is about 3.5mm x 142mm but could be stretched.
The biggest thin one
The smaller thick one seals the scrubber
So I guess it works either way around.
