I have been messing around wtih CoD4 X4 v3.0RC5 snipers only setup. I noticed the normal eXtreme HUD stats reflect nade & knife scores. With a sniper only server these stats are not tracked since all maps are (normally) no-crossing maps. So, I edited the _hudstats.gsc and removed the nade & knife stats and put all the stats neatly stacked on top of each other.
I have attached the edited _ex_hudstats.gsc file for any sniper server operators to add to thier server. Its easy. FTP this file to your server (make a backup of the current _ex_hudstats.gsc first) and overwrite the existing _ex_hudstats.gsc. This file is located at \Mods\cod4modfoldername\extreme fodler.
Here is what it looks like:
