Example of weight problems on node edit page

This image shows an example of problems I'm having getting elements on a node edit form to be organized in the order i would like them to be.

On it you can see that 'Menu' given a weight of 70 from my module, still appears with the 30 weights. Also, CCK fields don't seem to have weight associated with it all, so those form elements are being added after my module.
