Can’t set «class labi» of “Bobs_G4-1:^Back:St. Paul General:” to 2.

Try this:

tell application "Finder"
	set parentFolder to desktop -- Change this to "Bobs_G4-1:^Back:"
	make new folder at parentFolder with properties {name:"Test"}
	set label index of (result as alias) to 2
	open parentFolder
end tell
