The default order property seems deprecated according to the finder.json schema

    "finder_default_order": {
      "description": "DEPRECATED: Use “sort” property",
      "type": "string"
    },

The sort property seems to be the preferred option:

"finder_sort": {
      "description": "These are the options for sorting the finder",
      "type": "array",
      "items": {
        "type": "object",
        "required": [
          "key",
          "name"
        ],
        "additionalProperties": false,
        "properties": {
          "default": {
            "description": "Indicates if this should be the default sort option",
            "type": "boolean"
          },
          "key": {
            "description": "Rummager field name, with an optional preceding “-” to sort in descending order",
            "type": "string"
          },
          "name": {
            "description": "Label for the sort option",
            "type": "string"
          }
        }

so i guess something like

"sort": [
      {
        "key": "title",
        "name": "A-Z",
        "default": true
      }
]

@minhngocd I tried deploying the non-deprecated version (#2794) but it didn't work.

I think given none of the other finders use the sort key, and that there are five other live finders using the default_order key, let's just merge this one as-is and come back to it later.
