Not there either.

pacemaker-1.1.7-6.el6.x86_64

This constraint expresses the order of actions on two resources
or more resources. If there are more than two resources, then the
constraint is called a resource set. Ordered resource sets have an
extra attribute to allow for sets of resources whose actions may run
in parallel. The shell syntax for such sets is to put resources in
parentheses.

Usage:
...............
        order <id> score-type: <rsc>[:<action>] <rsc>[:<action>] ...
          [symmetrical=<bool>]

        score-type :: advisory | mandatory | <score>
...............
Example:
...............
        order c_apache_1 mandatory: apache:start ip_1
        order o1 inf: A ( B C )
...............
