There are two questionable assumptions you seem to make below:
(1) that FOP "chooses" (filters) metadata elements based on lang,
i.e., FOP implements the semantics of rdf:Alt;
(2) that FOP would fix-up non-conforming metadata;
Of course, the functionality in question is an extension to XSL-FO in
the first place, so it is *possible* that FOP could do these things.
However, it is not consistent with FOP semantics that it should do so,
since FOP does not make choices between *any* content based on
language, and since FOP does not perform *any* fix-ups for
non-compliant content.
You should perform the content selection process during the front-end
XSLT stage, or, if you are feeding FO directly to FOP, then do it when
you create the FO input file. That is, you should not expect this
extension to implement the semantics of rdf:Alt.
