In the past Scribus intermingled the techniques "subsetting" and "convert to
outlines/vectors".
Currently Scribus only supports two techniques: embedding and converting to
outlines. But
there are four combinations possible:

glyphs: |  "as is"        as outlines
____________________________
all     | embed        ./.
subset  |   ./.           outline

For OTF the "as is" approach is not possible since that possibility was only
introduced with PDF 1.6
(and that's not or rarely used in the printing industry). That's why some
fonts go straight to the
outline category.
Another limit is the number of glyphs. Some fonts are very large and have
thousands of glyphs.
In this case Scribus also decides to subset (and therefore outline) these
fonts, even if they are not 
in OTF format.

In the future we might also implement "as is" subsetting and embedding of
OTF fonts (by converting
them to TTF or CFF format).
