Well, not sure what command syntax you're using (strcmp with OnPlayerCommandText, ZCMD (recommended), DCMD or whatever), so i'll just give you the content of the command. It should look like this:
new string[64];
format(string, sizeof(string), "Kills: %d", PlayerKills[playerid]);
SendClientMessage(playerid, COLOR, string);
format(string, sizeof(string), "Deaths: %d", PlayerDeaths[playerid]);
SendClientMessage(playerid, COLOR, string);
//etc

Of course, you might have to replace COLOR with the color you want and PlayerKills, PlayerDeaths with the actual variables of your GM.
