How to sort Node type by custom Datetime property ISortablePagedList

Question

Hello
I have a "News" type in my own WLP Repository.
This type has a "publishedDate" date property like system "createdDate" property.
When I retrieve list of Nodes from repository I would like to sort CMPagedResult by my "publishedDate".
Something like
ISearchManager searchManager = ContentManagerFactory.getSearchManager();
Search search = new Search(“cm_ObjectClass = Newsl”);
search.setSortCriteria("publishedDate");
ISortableFilterablePagedList<Node> nodes =
searchManager.search(context, search);
doesn't work, also doesn't work if I use searchManager.postSearch method.
Also my property was maped on CM_NODE table(exists coloumn CM_PUBLISHED_DATE)
Please advice how can I make sort by my property.
