I'm using curl to connect a FileMaker 17 database.

I can do a query and sort on a given fieldName, so for instance, I can do something like:

```
"sort":[
    {"fieldName": "Work State","sortOrder": "ascend"},
]

```

What I cannot do, but what I'd like to do is something like:

```
"sort":[
    {"fieldName": "recordId","sortOrder": "ascend"},
]

```

recordId is not a "field", and so the above does not work. The syntax for this is not readily apparent in the FM documentation.
