This syntax should never have worked.

You need to either put a .tm_properties in each subfolder (templates, js, scss, and css) which has:

[ attr.untitled ]
fileType = «file type»

Or if you don’t mind targeting all files in each subfolder, you can leave out the attr.untitled, e.g.:

[ templates/** ]
fileType = 'text.html.mustache'

That said, it does seem like it would be nice to target both a file pattern and a scope selector, could possibly be done with : as separator, e.g.:

[ templates/**:attr.untitled ]
fileType = 'text.html.mustache'

I will consider such extension for a future update.

P.S. The {**,}/* syntax is redundant and ** should match the same (though this might not have been the case in earlier versions of TextMate’s file pattern matcher).
