as X has already suggested create a set of your own colo(u)r settings and switch to this. You can script this very easily as you just need the name string of whatever you've called it.

tell application "Adobe Photoshop CS2"
	activate
	-- Record current settings
	set User_CS to color settings
	-- Apply your settings
	set color settings to "Marks Test"
end tell
--
(*do your processing here*)
--
tell application "Adobe Photoshop CS2"
	-- Put back settings
	set color settings to User_CS
end tell

(*or apply/convert profiles*)

tell application "Adobe Photoshop CS2"

	tell document 1
		-- Apply a colour profile
		if color profile name ≠ "Europe ISO Coated FOGRA27" then
			set color profile name to "Europe ISO Coated FOGRA27"
		end if
		-- Convert to colour profile
		if color profile name ≠ "U.S. Sheetfed Coated v2" then
			convert to profile �
				"U.S. Sheetfed Coated v2" intent absolute colorimetric �
