[support] Rules on update node use same value for $node and $node_unchanged

Hi all, I have two content type "foo" and "bar". When I update a "foo" node I need to get two values from a foo's fields (cck integer and node reference) and update the referenced node of type "bar". To do this I use "rules" module with a PHP custom function, but I have a problem: $node and $node_unchanged have the same values. I have tried the token version (always rules module): "[node:field_costo_importo-raw]" and "[node_unchanged:field_costo_importo-raw]". But I have the same result: both have the same value. Where is the error ?
