Sorry for the slow response.

My key question is, has the Government ruled which is correct?
 - Short answer : NO

As a mother tongue user of Burmese, <RA, SIGN U, SIGN AI> is a common
combination but <RA, SIGN AI, SIGN U>  is not. But there are some users who
might use <RA, SIGN AI, SIGN U>  in the place of <RA, SIGN U, SIGN AI>.

For <SIGN AA, SIGN AI> and  <SIGN AI, SIGN AA>, I have not seen these as
common combinations used in recent years although both of these are valid
