Which says you need to include both this line:

<meta property="ibooks:specified-fonts">true</meta>

in the opf and an XML file com.apple.ibooks.display-options.xml

AFAIK, you don't need to add that line in the opf file. The xml file should be unmanifested.

The com.apple.ibooks.display-options.xml file is attached with this post. Place the xml file in the META-INF folder and iBooks will recognise the embedded fonts.
