You can see rule priority through View > Sort By > Precedence. It's mostly that narrowly-defined rules have priority over more general ones.
The rules can't be reordered, but I think you could accomplish the same thing by disabling the default rule and substituting something different. Try disabling the allow-all rule from local network (temporarily at least), and see how many processes really need to receive such communications. There might be only a few; allow them individually and your deny rule should work.
