To clear it more I made my assumptions based on this 
A,B and C are LTR labels 
Display order based on UBA(UAX9).

Actually we don't know how they will be displayed, it depends on the
directionality of each label and on what algorithm we will be using.
it could be ABC if all the labels are LTR and we are using UAX9 to
display them,  but it could also be ACB if A is LTR, B, C are RTL and
we are using UAX9 to display them.

Same here, we can't assume anything.
