Blank types have nothing for _Sort and seem to be sorted by _nodeID. That's awkward for blank type columns in the Data Explorer.
Why not sort blank types by key values in key order, like for computed / groups? Even if you didn't add UI for re-arranging blank types' key order in the model table, as long as blank type values are presented in key order in the Data Explorer, a column sort would look right in the Data Explorer and would be useful.
