You're going to have to find other tools to fix this.
I often run into similar issues with FLAC downloads from bandcamp.com. They name individual files oddly, and I always have to rename all tracks with every download. I am a licensed user of Directory Opus, and it handles batch renaming of similar files quickly and easily. I am sure there are other tools that will do that too.
Once all the file names match the track titles as closely as possible, I then use my batch tag editor to set the tags per the file's path and name. Once that is done, my work is 95% complete.
