It seems to me that as far as Ogham goes the positioning of successive glyphs is more comparable to the way a graphics program will position text along a path (allowing text to go in a circle, for example) than the differences between LTR, RTL, vertical and boustrophedon scripts. The text isn't composed of a BTT passage, a LTR passage and a TTB passage, but of a single passage which follows a path which changes through those three directions.
