Access Annotation Plot Scale in AutoCAD MEP 2010 Using Lisp

[xspacex]

I use to be able to access the annotation plot scale in AutoCAD MEP 2008 using lisp from the dictionaries as shown below, but this does not work in AutoCAD MEP 2010. I am hoping that someone knows how I can access the anootation plot scale found under "drawing setup" in MEP 2010? Thanks.

(cdr (assoc 42 (dictsearch (cdr (assoc -1 (dictsearch (namedobjdict) "aec_vars"))) "aec_vars_dwg_setup")))

I was wondering if somone knows how I can access the "annotation plot size" found under "drawing setup" in AutoCAD MEP 2010 using activex...
