Thom Blake is right about why it's keeping the same values for the array. one option for solving this is to set the default value in the initializer

                "priority": "Normal"
            },

            initialize: function(){
              if( !this.get('tags') ){ 
                this.set({tags: new Array()});
              }
            }

        });
