Hi,
I had exactly the same problem in writing script file for turning the Wire No layer off. Thanks for your comprehensive guidance.

I too am looking to write a script to be able to change the CAT attribute to a different height and width. It is not one of the options in the project wide utility. Thanks in advance for any help
The script might not work considering that the "Change attribute size" command (AEATTSIZE) calls a window. Alternatively you can modify the blocks and swap them project wide or use the "Change Attribute Size" command on each drawing and select "By name" to change all the atributes with the same name (in your case CAT).

Bill Fane is good at explaining the skill. I once emailed him and his response is in the attached Notepad document. Work your way through the step by step process and you will probably be able to figure it out.
