TYPO3 Core

I'm not sure if things get too complicated with renderPriority. Maybe I have to think again about this one - it's tricky, but is a real scenario.

If only a few plugins are affected you can "postpone" the rendering process of a USER_INT with a wrapping COA_INT.

Initial example:
10 = COA
10 {
10 = USER_INT
10.userFunc = pluginA->main
20 = USER_INT
20.userFunc = pluginB->main
}

Changed exampled, with pluginB getting postponed:
10 = COA
10 {
10 = USER_INT
10.userFunc = pluginA->main
20 = COA_INT
20 {
10 = USER_INT
10.userFunc = pluginB->main
}
}

Not in core list, and solution proposed by Olly seems reasonable.
