I'm not sure if I follow. You have rules that you want to share across the organization in one ruleset and you have division level rulesets as well to refine the behavior of the org rules you made. In which application do the division rulesets reside? The org app, or the custom apps on top? You probably don't want the rulesets to be in multiple applications at the same time because if you have AppA and AppB built on top of org, both with DivRS:01-01 in them, if someone changes App A to be built on top of AppB, the rulset DivSR would be in the ruleset stack twice. Assuming that's your scenario, you'd be better to move DivRS into AppDiv, built on org, with AppA and AppB separately built on AppDiv.
If I'm completely misunderstanding what you are describing (and I'm 100% I got things right) then please add a couple of screen shots so that we can see how all the pieces relate and what the error you're getting is.
