Is it possible to sort an array of maps on multiple criteria?

For example could I sort the below by count & then title? I tried the addSortCriterion but that gave me an error.

#set ($menuItems= [])
#set ($tmp = $menuItems.add({"title" : "item1", "count" : 5, "url" : "http://www.google.com"}))
#set ($tmp = $menuItems.add({"title" : "item3", "count" : 3, "url" : "http://www.google.com"}))
#set ($tmp = $menuItems.add({"title" : "item4", "count" : 2, "url" : "http://www.google.com"}))
#set ($tmp = $menuItems.add({"title" : "item2", "count" : 3, "url" : "http://www.google.com"}))


#foreach ($item in $_SortTool.sort($menuItems, 'count:desc'))
<a href="$item.url">$item.title</a>
#end

   Hi,

   The Sort Tool can sort by multiple properties by supplying them as an array. For example:

   #foreach ($item in $_SortTool.sort($menuItems, ['count:desc', 'title:asc']))
   <a href="$item.url">$item.title</a>
   #end
   

   For information on this functionality can be found on this page.

   Please let me know if you have any questions.

   Thanks!
