Lamar Owen nailed it in his post: renaming a file means updating its
directory entry and hence requires write permission on the directory, not
the file - which you have as a result of the "other" permissions on the
directory:

drwxrwxrwx   7 root root  4096 Mar 10 13:35 temp

If you want the full story, I have an article on my web site (part of a
magazine series I wrote, years ago) which explains permissions in detail:
