Eric,
I think there is a bug in the way the exporter handles odt fragments.

Explanation: Maxima can print output in mathml. Your question inspired
me to try to craft an example. I came up with the attached org file.

The first two subsections of it exports fine to html (replace "export
odt" with "export html"). But when I export to odt, something weird
happens: contents.xml contains the fragment of mathml, but it is not
displayed in libreoffice. On the other hand, the snippet in the third
sub-section, that is saved to file, is handled correctly (the somewhat
mangled formatting is a bug in Maxima's mathml printer).
