The "hierarchy of gaps" (better "ordering" IMO) is implicit in the concept of "significance": to distinguish which gap is significant and which is not you need a measure to compare them. If you have a measure, you have the ordering. For example, it is implicit in the concept of natural numbers that 
Hence, the *criterion* is still one: the significance of gaps.
