RTC VCS changes priority/order

I'm working on script which is used to apply patches on repository based on changes checked in into RTC repository. Unfortunately I have some issues connected with API which returns me changelists. Everything looks well until we try to make more operations on file such as: modify and reparent, reparent and delete parent folder etc. Is there any way to make API return correct order of operations? Basically it looks like API returns only 1 change per file in changelist and this could be a problem.
