Soft constraints

Hello. I am trying to give a priority to one vehicle for a stop over another. I’ve implemented a soft constraint where :

    public double getCosts(JobInsertionContext insertionContext) {
        double penalizeScore = 0.0;

        if (vrpTasks != null) {
            for (VrpTask vrpTask : vrpTasks) {
                if (vrpTask.getId().equalsIgnoreCase(insertionContext.getJob().getId())) {
                    if (!insertionContext.getNewVehicle().getId().equalsIgnoreCase(vrpTask.getPrioritizedVehicleId())) {
                        penalizeScore += 10000;

        return penalizeScore;

I’ve set penalty to 10000 but I’m not sure if this is a right way to implement it. Can anybody tell me if there is something I’m missing ? Thank you in advance.
