What about when there are agents with difference source codes and different preferences?

Set aside different preferences, because I have no idea how to deal with that. It seems like just having different source codes makes things very difficult.

You used "1" and "2" as your indexical labels, which come with a very obvious order. But suppose that Omega labeled one agent ♠ and the other agent ♣. If you and your opposite have different source codes, you have no idea how your opposite internally represents the symbol that they received. For example, you certainly have no guarantee that the two of you order these in lexicographically the same way. So how could you possibly coordinate on a tie-breaking strategy?

You can't, unless you can communicate in some way, such as by talking to eachother or reading eachother's source code. In that case it's easy.
