Hello sgnormo, I'm relying on my memory, hope this information will be accurate enough..
As far as I can remember you should be able to reorder statements as you said, by drag and drop.
Check the following:
- What's the policy strategy? Maybe if it's "all matching rules" it'll be disabled since order won't really matter
- Is this in a configuration partition? Are you using "ALL" partition view by any chance? Make sure to move in correct partition view
- What's your user privilege? Operations might be limited for non-admin roles
Also, there's built-in help in "Help" menu once you're in the policy configuration view. Check what's stated for "IDs" .. or whatever the rule ID is called
Hope this helps
