Sort files by filename

[Mark Haney]

This is really a general linux question. I have a series of files in a 
format like this:

XXXX20070515_112011_942_10.bz2
XXXX20070515_112011_942_12.bz2 etc,

and I am trying to find a way to do 2 things, one, sort these files in 
order, and then once in order, find the files that are numerically 
missing based on the last 2 numbers in the file name.  So if I have (as 
above I want to know that file XXXX20070515_112011_942_11.bz2 is 
missing.  Can someone get me started on this, I'm stumped.
