Currently there is no option to configure the priority of front controller plugins loaded via Zend_Application_Resource_FrontController

The suppied patch, or a similar piece of code would allow the following config file options

resources.frontController.plugins.foo = "My_Plugin_Foo"

resources.frontController.plugins.foo.class = "My_Plugin_Foo"
resources.frontController.plugins.foo.priority = 99
