The implementation issue for embedded Mongolian is confused by the fact that the script is currently implemented in OpenType fonts as if it were a LTR script, i.e. the outlines are designed left-to-right in the glyph space rather than top to bottom, and then the text blocks are rotated for vertical display. This is itself a questionable practice, although it obviously simplifies font development and line layout for Mongolian. This means that RTL embedding would require, as Peter points out, a 180 degree rotation from the 'normal' direction of the text, rather than a choice between a 90 degree rotation either clockwise or counter clockwise depending on the direction of the surrounding horizontal text.
