Yet another option could be to use more parameters:
-- b is the button number (obligatory)
-- [b may be also misused for any positive integer]
-- clicking the control with that handler leaves x empty
on mouseUp b,x
 switch x
    case ...
    case ...
    default -- x is empty
      -- the direct-click code, use b
   end switch
end mouseUp
