I have put every command I have found on google into my server's config, and it doesn't seem to work.

These are the commands that I have tried but had no success with:

set scr_tdm_score_kill "1000"
set scr_tdm_score_headshot "1000"
set xp_scale 4
set developer_script 1

Is there any way to get this to work? I've tried using the RCON to set the command but it just says the dvars are read only. I have seen many servers do custom XP values, even some with their server names before the XP value.
