I checked this and the information is correct. Scribus uses Freetype to
access fonts and Freetype only accesses kerning information from AFM
files and TTF kern tables.
If an OTF font is not Truetype based but CFF based, it does not have a
kern table but a GPOS table, which is not supported yet. From the OTF
"OpenTypeTM fonts containing CFF outlines are not supported by the
'kern' table and must use the 'GPOS' OpenType Layout table."

Also true. The new text engine will use GPOS tables.
