How to remove files that bak0 is in file name

I have filenames with .Bak.mp3 in them how can i sort them with tools

Looking at the topic and the text, it is not quite clear what you want: sort or remove.
To see such files in MP3tag, I would filter for them with
%_filename% HAS .bak
and if that does not work
%_filename_ext% HAS .bak

What about using your file explorer with a search mask like *bak.mp3 or *bak0.mp3?
To remove: Mark all items in the search result and press Delete
To sort: Press on the column header for which you want to sort (Date? Size? Name?)
