If you want to return a list of entities or properties in combination with a count you will need a group by. In criteria this is done through ProjectionList and Projections. e.g.

    final ProjectionList props = Projections.projectionList();
    props.add(Projections.groupProperty("giftID"));
    props.add(Projections.groupProperty("giftName"));
    props.add(Projections.count("giftID"), "count"); //create an alias for the count
    crit.setProjection(props);

    crit.add(Order.desc("count")); //use the count alias to order by

However, since you're using ProjectionList you will also need to use AliasToBeanConstructorResultTransformer.
