Actually, from what sources I've seen, while the Philippine scripts were sometimes written as if they were bottom to top when using materials other than paper, it was always read left to right. It was a case of it being more convenient with the materials used to write it bottom to top, but it was never intended to be read that way.
As I said, it was written from-the-body-out. -- Michael Everson * * Everson Typography * * http://www.evertype.com
