Is an extension of the min attribute possible, which only allows greater?

Yes, you can use something like this.

_.extend(Backbone.Validation.validators, {
          greaterThan : function (value, attr, minValue, model) {
                var val = parseInt(value, 10);
                if (_.isNaN(val) || val <= minValue) {
                    return this.format("{0} must be greater than {1}",
                        this.formatLabel(attr, model), minValue);
                }
            }
}
