No The number you have in this, & subsequent ties, is the position on their board that you were drawn out. What I mean by this is I think we were the 26th tie to be drawn so we become number 26 for this round. If in the draw tomorrow we're the 2nd tie to be drawn, the winners of our tie will be number 2 for the next round.
we are number 28 see link http://www.thefa.com/TheFACup/TheFACup/NewsAndFeatures/Postings/2008/01/FAC4_ballnumber.htm

No It's the number of the game in which it was drawn before - not the number in alphebetical order (if you see what I mean)
