You could add the points with the timer + GetTickCount()

pawn Код:

new lasttick[MAX_PLAYERS];

public TimerFunc(playerid)
{
    if(GetTickCount() - lasttick[playerid] >= 1000)
    {
        SetPlayerScore(playerid, GetPlayerScore(playerid) + 1);
        lasttick[playerid] = GetTickCount();
    }
}

This will check in addition, if really more than a sec went since the player got his last point. So the max tolerance will be 1 point.
