I think that machinery is in this line of files.el:basic-save-buffer:
(set-file-modes buffer-file-name setmodes)
[and similar lines elsewhere in basic-save-buffer's subroutines].
Perhaps Tramp sabotaged some of the code that tells Emacs there's a need
to set file's permissions, or maybe set-file-modes itself fails under
Tramp?
