You're correct and this is exactly why it's not the same as renaming mp3 to flac.

Mp3tag doesn't support codec detection inside Ogg containers currently and assumes Vorbis by default. It's on my list, but for the time being, Opus needs to come with the \*.opus file extension to be usable inside Mp3tag.
