I think the filters are tried by their occurence in the configuration.
If that is really the case, we could implement simple ordering based on
filter flags, e.g., decrease priority for ALIEN and 3RDPARTYFILTER and
increase it for filters that are both IMPORT and EXPORT. That would put
.odt before .docx and that before .fb2 (which is the one from libe-book
that checks for zip content).
