Would down-facing/ sealed be considered a 3rd order enclosure?

No, how you face the driver shouldn't add an order.

But a down facing sub interacts with the ground.

This alters the spectrum in recorded output.

But the natural roll off DB could define the enclosure order?

The “order“ represents energy storage. The floor doesn’t store energy, it reflects energy.

Any direction you orient a sub can affect it's output, this true even more so in a car. Nevertheless it doesn't add an order and generally doesn't affect roll off.
