If it's for shielding, the plate is at higher potential than the grid.
True, the plate is at higher DC potential. But signal wise, the plate presents lower impedance-to-ground than the grid which the cap is coupling to. Ergo, better shielding is obtained with the outside foil connected to the plate.
