Format Text using Style Sheet in Quark 5.0

I need to be able to format Text in Quark 5.0 using the Style Sheet. Here is what I have so far.

tell application “QuarkXPress™”
tell paragraph 1 of story 1 of document 1

	set style to {style sheet:style spec "RegBodyC"}
	set style to {on styles:{superior}} --This works but Style Sheet doesn't
end tell

end tell

Any help would be greatly appriciated!!!
