Sorting by Id doesn't seem to work with AppSeach/Enterprise search. Please see the reference UI sort by id. For some reason the id starting with b is before the id starting with a.
The UI generates the labels from the document properties - so think it's just capitalized in the label. I'm seeing this same behaviour in my own UI too
