applescript illustrator page setup

I know this is really simple but does anyone know a script to set the document to US Letter and then set the zero point to the lower left corner of the screen. I have this book “Adobe Illustrator Scripting with Illustrator and VB” and it really stinks. None of the scripts work, mow Im working in Ill CS2 and OS X so I think that has something to do with it.

I guess all I need to know is, if the ruler orientation of an illustrator document was changed, is there a command to set it back to the bottom left corner of the document

tell application "Illustrator CS"
	set ruler origin of document 1 to {0.0, 0.0}
end tell

I wish this forum had points or a rep builder. Thanks for the help.
