Rules with the same priority are on the same level and the order of these rules is not fixed and may change. If you want to make sure that a rule will be added after another one, use a low priority for the first and a higher for the following.

I believe the priority feature is introduced in a version  later than what is in CentOS 7. However, I believe the 7.3 update (in beta now for RHEL) has a version that supports priority.
