MathML needs to work with vertical text.

What exactly does this mean?  Is it a left-to-right block containing mathematics in a vertical line?  I've asked some Japanese epub experts about this exact issue and was told they use left-to-right for mathematical texts.  I'd love to see a sample (scan of a page) of vertical writing with modern mathematical text embedded.

Basically, you should rotate clockwise by 90 degrees for vertical-* values. Please take a look at spec:
However replaced content involving text (such as MathML content or form elements) should match the replaced element's writing mode and line orientation if the UA supports such a vertical writing mode for the replaced content.

I have some scan samples collected at:

Hope this helps.
