I doubt anything got changed intentionally wrt object names. Could be a bug. Haven't tested it.
In the meantime, try using the PrefixDeploymentSorter in your conf/jboss-service.xml rather than the plain DeploymentSorter (you need to uncomment the prefix sorter and comment the original out). This allows you to explicitly set the deployment order of your packages by naming them in -package.xAR where is an integer indicating the order. This is quite a bit more convenient than using the tag for simple ordering.
