That's because XSLT always operates on source tree not on sorted nodes. 
Getting correct numbers would mean overwriting existing code to use 
position() function to get bibliography number.

I think that your requirements are so complex that you would do better 
using some citations management tool which is able to sort and export 
bibliography entries into DocBook. I think that refdb from Markus 
Hoenicka can do that and there are probably also other systems.
