I don't understand the problem; you can return whatever you want:

on hellotest pTheNumber
	if not isnumber(pTheNumber) then
		return "ERROR: '" & pTheNumber & "' is not a number."
	end if
	...
end hellotest

then in the calling handler, just test the result:

	...
	hellotest someValue
	if the result is not empty then
		handleError the result
	else
		handleSuccess
	end if
	...
