This will solve the warnings:

pawn Код:

CMD:gunpack(playerid, params[])
{
    if(GetPlayerScore(playerid) >= 0) // regular player
    {
        GivePlayerWeapon(playerid, 22, 100); // you may change the weaps here
        GivePlayerWeapon(playerid, 25, 100);
        GivePlayerWeapon(playerid, 29, 100);
    }
    else if(GetPlayerScore(playerid) >= 300) // 300 score
    {
        GivePlayerWeapon(playerid, 24, 100);
        GivePlayerWeapon(playerid, 27, 100);
        GivePlayerWeapon(playerid, 32, 100);
    }
    else if(GetPlayerScore(playerid) >= 500) // 500 score
    {
        GivePlayerWeapon(playerid, 31, 130);
        GivePlayerWeapon(playerid, 34, 100);
        GivePlayerWeapon(playerid, 28, 230);
    }
    return 1;
}
