I did a deep dive into one of my tagged .wav files.
I first used the Linux strings command to extract sequences of 4 or more ASCII characters from the file and then did a little grep'ing through the result.
Turns out the metadata created by dBpoweramp are stored in an LIST_INFO chunk, just as the Wikipedia article suggests they should be. Here's a raw dump of the strings content of that chunk:
What we see here are some RIFF INFO fields with ids such as IPRD and IARTF followed by ID3v2.3 fields with ids such as TIT2, etc.
It would seem that the MPD plugins are able to locate this chunk and use the information to populate its database for that track.
The fact that, in your case, mediainfo could find the metadata in your .wav file but MPD plugins couldn't suggests to me that Kid3 hung an ID3v2.3 tag ("tag" in the sense of the specification-defined block of metadata) somewhere else. I've seen a similar thing happen before with a misconfigured tag editor applied to a FLAC file.
Bottom line: WAV files can be tagged successfully for use in moOde but your issue suggests Kid3 isn't the right tool to do it (or at least wasn't configured to do so, if there are relevant configuration settings. Don't ask; I have no idea what/where).
