Yes!  I found this post when Googling how to reply and have just figured it out.  All AirTable plans can add the Vega-Lite extension, and the page https://vega.github.io/vega-lite/docs/sort.html#specifying-custom-sort-order is a good start.

In my case I have a table called "Issues", with a field called "Problem".

The default definition after adding that exentsion and choosing the correct table is:

{

    "$schema": "https://vega.github.io/schema/vega-lite/v4.json",

       "title": "Issues",

       "width": "container",

       "height": "container",

       "mark": "bar",

       "encoding": {

           "x": {

               "field": "Problem",

               "type": "nominal"

         },

         "y": {

               "aggregate": "count",

               "type": "quantitative"

         }

     }

}

 

And that gives a normal bar chart:

 

 

 

Adding a sort definition to x, like:

"sort": {"op": "count", "order": "descending"}

 

so that the code is now:

{

    "$schema": "https://vega.github.io/schema/vega-lite/v4.json",

       "title": "Issues",

       "width": "container",

       "height": "container",

       "mark": "bar",

       "encoding": {

           "x": {

               "field": "Problem",

               "type": "nominal"

               "sort": {"op": "count", "order": "descending"} 

         },

         "y": {

               "aggregate": "count",

               "type": "quantitative"

         }

     }

}

 

This gives a Pareto chart:
