In elasticsearch-1.3.7 I want to run a top_hits aggregation sorted by each top_hits geolocation distance.

Here is how I am using the top_hits agg, I have everything working and sorting with a script but I can't figure out how to sort by geolocation distance:

        {
            "aggs": {
                "rollup": {
                    "terms": {
                        "field": "offer_store.store_key",
                        "size": 10,
                        "order": {
                            "order_by_value": "desc"
                        }
                    },
                    "aggs": {
                        "offers": {
                            "top_hits": {
                                "size": 1,
                                "sort": [
                                    {
                                        "offer_value": {
                                            "order": "desc"
                                        }
                                    }
                                ]
                            }
                        },
                        "order_by_value": {
                            "max": {
                                "field": "offer_value"
                            }
                        }
                    }
                }
            },
            "size": 1,
            "from": 0
        }

This was all of the documentation I could find on sorting by a metric, but nothing about geolocation.
