This is an example how to do it, but it isn't very effective because you don't have to be in a truck all the time to get score.

pawn Код:

forward GiveScore();

//under OnGameModeInit
SetTimer("GiveScore", 60000, true); // timer for every 1 minute

public GiveScore()
{
    for(new i=0; i < MAX_PLAYERS; i++)
    {
        if(IsPlayerConnected(i) && IsPlayerInTruck(i)) // You need to get or make yourself the IsPlayerInTruck function
        {
            SetPlayerScore(i, GetPlayerScore(i) + 1);
        }
    }
}
