Best Centos documentation I can find for that is here:
http://www.centos.org/docs/5/html/5.2/Cluster_Administration/s1-clust-rsc-sibling-starting-order-CA.html

"... a non-typed child resource is started and stopped according to its 
order in /etc/cluster.cluster.conf.  In addition, non-typed child 
resources are started after all typed child resources have started and 
are stopped before any typed child resources have stopped."

Also see the following 2 pages in the documentation I linked above. 
This is virtually the same as in the RHEL6 guide and so should apply to 
Centos6.

I recommend raising a bug for this issue.

On a slightly different topic, perhaps see if pacemaker can do what you 
need it to.  http://clusterlabs.org/doc/
