Ok, what you just did will tell Sugar that Scratch is able to open
files with the mime type 'application/x-scratch-project'. But this
will not affect the icon of those files.

Don't know myself :/

Well, activities are installed by a normal user so that file won't be
modified. Instead, the cache will live in ~/.local/share/mime

Yes: update-mime-database ~/.local/share/mime
If you want to get the details and fully understand how this is done,
you can check this code:
That gets executed when a bundle is unpacked and registered in the
shell. As you can see, if a file activity/mimetypes.xml is found in
the exploded dir, a symlink will be made to this file form the mime
dir and the updater script will be run.
