Just an example tip which simply works with a counter, hope helps you.

a) Do you really need the sorting stuff? I didnt mess with that. 

b) the counter:

[rodolfoap] /home/rodolfoap > for n in $(seq 10 40); do touch XXXX20070515_112011_942_${n}.bz2; done
[rodolfoap] /home/rodolfoap > rm XXXX20070515_112011_942_11.bz2 
[rodolfoap] /home/rodolfoap > rm XXXX20070515_112011_942_22.bz2 
[rodolfoap] /home/rodolfoap > rm XXXX20070515_112011_942_33.bz2 
[rodolfoap] /home/rodolfoap > for n in $(seq 10 40); do if [ ! -e *_${n}.bz2 ]; then echo NOT FOUND: $n; fi; done
NOT FOUND: 11
NOT FOUND: 22
NOT FOUND: 33
[rodolfoap] /home/rodolfoap >
