You have to override BarNumber: 'break-align-symbols
and for centering above the BarLine, BarNumber: 'self-alignment-X

Changing 'break-align-orders is the way. But the IR shows only how to
change it for all possibilities (i.e end-of-line, middle-of-line and
begin-of-line) via make-vector 3
That's not what you want here. You have to rearrange the whole list.
Having done so, there's need to readjust some spacing of the
TimeSignature via TimeSignature: 'space-alist.
I've no idea why I had to differ between end-of-line and begin-of-line.
