I also just want to let you know you don't need to do
IsPlayerInRangeOfPoint return 1
return 0
You can simply return IsPlayerInRangeOfPoint, since that returns false / 0 if he's not in range, and true / 1 if he is.

IsPlayerInRangeOfVehicle(playerid, veh, Float: range)
{
    if( !IsPlayerConnected( playerid ) || !IsValidVehicle( veh ) ) return 0;
    new
        Float: x,
        Float: y,
        Float: z
    ;
    GetVehiclePos( veh, x, y, z );
    return IsPlayerInRangeOfPoint(playerid, range, x, y, z);
}
