Yeah, this is usually the biggest reason why sort() isn't very useful - since it's almost completely useless for sorting via the value of a particular field of a cdt/dictionary/map, and requires some hoops to jump through in some other even fairly simple use cases for no particularly good reason.

This is the best way.

Agreed. It would be good to see it evolved so that you could declare the desired sort order (right now you have to sort and then use fn!inverse() to get a descending-order result. Also being able to declare which item in, say, a map you want to sort by would be useful, as would nested sort orders (e.g. sort by A, then E, then C, then D in a map that had keys of A, B ,C D, E)

Right now sort() if not officially supported so if you use it and there's an issue after, say, an upgrade, you won't get any support from Appian to address you issue.

Yupp! I know that pretty well. Just one of many requests which we have from Appian.

I hope you know you shouldn't be using undocumented functions.

You can also use Sort Utilities plugin, only if you are okay with dependency on a custom plugin.

However, I believe it is high time Appian should introduce OOTB documented version of the hidden sort() function, instead of forcing us to first convert the data into key value pairs and then use todatasubset and pagingInfo just to apply sorting to a list of numbers.

There is no direct function. You can use todatasubset() paired with sortInfo() to get the desired result.

a!localVariables(
  local!array: a!forEach(
    items: ri!array,
    expression: { utls: fv!item }
  ),
  todatasubset(
    arrayToPage: local!array,
    pagingConfiguration: a!pagingInfo(
      startIndex: 1,
      batchSize: - 1,
      sort: a!sortInfo(field: "utls", ascending: ri!isAscending)
    )
  ).data.utls
)
