Copy Scrivener Files from local Dropbox Folder

Hi, i want t start with a simple example, and copy a single .scriv file from the local Dropbox folder, to my Documents, if modified. It seems that Dropbox treats the Scrivener-Document not as a single File, but as a folder - so only a file within that folder is changed, ...
Dropbox doesn't update the local modified date for the whole file, if the remote changed scrivener file is synced. So, if i use the rule "Date Last Modified" - "did change" to trigger the copy, nothing happens...
I think the Problems is that the File is an Archive.
Is there a way in Hazel to determine if a document in the packed folder has changed and then copy only that document, taking the document structure into account? Can Hazel handle archives and update them?
