BIDI percentage sign

[James Lin]

Hi
I looked through the Unicode standard Annex #9 and unable to find out if percentage sign "%" should reside on the LEFT of the numeric character or RIGHT?

My understanding is if the numeric is in Latin or Western Arabic number, 1 2 3 4 5 6 7 8 9 0, "%" sign should be on the RIGHT: 12%, 54%;   For Eastern Arabic, "%" sign should be on the LEFT:  %٩٦٥

Is this correct? 

Thank you
