I've run into a weird issue with nested sorts. When specifying a sort as such:

```auto
"sort": [
    {
      "variations.price.regular": {
        "mode": "min",
        "order": "asc",
        "nested": {
          "path": "variations.price"
        }
      }
    }
  ]

```

It works as expected and sort values like `"sort" : [500]` are returned. However when specifying a nested sort with a `filter` as such:

```auto
"sort": [
    {
      "variations.price.regular": {
        "mode": "min",
        "order": "asc",
        "nested": {
          "path": "variations.price",
          "filter": {
            "term": {
              "variations.inventory.shop_id": 1
            }
          }
        }
      }
    }
  ]

```

It does not work as expected and sort values like `"sort": [9223372036854775807]` are returned.  
Below is a full reproduction of this issue as a Kibana script:

Am I doing something wrong when adding the filter within the nested sort? The issue seems similar to [Sort is out of order - using Nested Filter](https://discuss.elastic.co/t/sort-is-out-of-order-using-nested-filter/159070) but there were no responses on that thread.

All tests run with Elasticsearch and Kibana 6.8.3 docker containers.

For any future forum wanderers that end up here, we ended up solving this by combining the two nested types into a single nested type. Below is a transformation of the above example similar to what we ended up doing:

```auto
