   　test1:
   　　Metadata > Priority > 10.0
   　test2:
   　　Metadata > Priority > 40.0
   　test3:
   　　Metadata > Priority > 5.0
4. Go to default site > any page, and Place Asset Publisher Portlet
5. Go to default site > any page > Asset Publisher Portlet > Configuration, and edit as follows and Save
   　Set Up > Asset Selection > Ordering and Grouping
   　　Order by [Priority] [Descending], And Then [Title] [Ascending]
6. Go back to page and check the contents order in Asset Publisher
