We generally categorize files with something like

find /mnt/repair | while read f; do 
	F=`file $f | cut -f2- -d:`
	mkdir "/tmp/r/$F"
	ln -sv "$f" "/tmp/r/$F"
done

It will nicely sort your files into directories by file-type (ignore
errors).  Its not the best, but certainly a good start.  Also note that if 
somewhere in /mnt/repair two files with the same type have the same name, 
you will have a name collision.  Hopefully your preliminary restore 
software gave unique names to the files.  

Without additional knowledge of /what/ you are looking for, I'm not sure
what to suggest.  If the dentry system is indeed completely(!?) gone, then
I would give up on finding names and start looking for content.  If its
really important, the name can be changed ;)

At least then you end up with directories like
