Nested Inner Hits sorting

Elastic Stack Elasticsearch
1

According to documentation (https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-inner-hits.html#nested-inner-hits), inner hits returned can be sorted, and default sorting is score. I have a document with nested documents indexed in a defined order, and I would like to query the documents with inner hits returned in the indexed order. I realized however, that it is returned in revered order.

Here is one returned hit:
"hits": [

{
    "_index": "myIndex",
    "_type": "myType",
    "_id": "AVcPID001OHiI-svKuW9",
    "_score": 37.105354,
    "_source": {},
"inner_hits": {
    "innerObject": {
        "hits": {
            "total": 4,
            "max_score": 1,
            "hits": [
                {
                    "_index": "myIndex",
                    "_type": "myType",
                    "_id": "AVcPID001OHiI-svKuW9",
                    "_nested": {
                        "field": "innerObject",
                        "offset": 3
                    },
                    "_score": 1,
                    "_source": {
                        "id": 3123636
                }
                ,
                {
                    "_index": "myIndex",
                    "_type": "myType",
                    "_id": "AVcPID001OHiI-svKuW9",
                    "_nested": {
                        "field": "innerObject",
                        "offset": 2
                    },
                    "_score": 1,
                    "_source": {
                        "id": 4797314
                    }
                }
                ,
                {
                    "_index": "myIndex",
                    "_type": "myType",
                    "_id": "AVcPID001OHiI-svKuW9",
                    "_nested": {
                        "field": "innerObject",
                        "offset": 1
                    },
                    "_score": 1,
                    "_source": {
                        "id": 4538830
                    }
                }
                ,
                {
                    "_index": "myIndex",
                    "_type": "myType",
                    "_id": "AVcPID001OHiI-svKuW9",
                    "_nested": {
                        "field": "innerObject",
                        "offset": 0
                    },
                    "_score": 1,
                    "_source": {
                        "id": 5653177
                    }
                }
            ]
        }
    }
}

}
]

So you can see the inner hits have the same score 1 (since my request was "match_all"), and i didn't define any sorting, just set the size 4. But the "offset" indicates 3 than 2 than 1 than 0, which is the reverse order of the nested documents.
How can I get my inner hits in the right order? I tried by the way to sort them by different fields (String, integer) and I always get them in the same order.

My elasticsearch version is 2.0.1
