To learn I have to do everything again and try to not cheat. 
Here are some NSArray handlers that return AppleScriptObjC objects.
Its a early version and slow progress.
Some will return NSArray and other could return NSString/NSArray.
New to me is: Key-Value Coding Programming Guide

* valueForKeyPath: @distinctUnionOfObjects.self
* When you specify the @distinctUnionOfObjects operator, valueForKeyPath:
* creates and returns an array containing the distinct objects of the
* collection corresponding to the property specified by the right key path.

* valueForKeyPath: @avg.self
* When you specify the @avg operator, valueForKeyPath: reads the property
* specified by the right key path for each element of the collection,
* converts it to a double (substituting 0 for nil values), and computes
* the arithmetic average of these. It then returns the result stored in
* an NSNumber instance.

* When you specify the @count operator, valueForKeyPath: returns the
* number of objects in the collection in an NSNumber instance.
* The right key path, if present, is ignored.

on arrayWithCountString:anArray

(**
* valueForKeyPath: @max.self
* When you specify the @max operator, valueForKeyPath: searches among
* the collection entries named by the right key path and returns the
* largest one. The search conducts comparisons using the compare: method,
* as defined by many Foundation classes, such as the NSNumber class.
* Therefore, the property indicated by the right key path must hold
* an object that responds meaningfully to this message. The search
* ignores nil valued collection entries.

* valueForKeyPath: @min.self
* When you specify the @min operator, valueForKeyPath: searches among
* the collection entries named by the right key path and returns the
* smallest one. The search conducts comparisons using the compare: method,
* as defined by many Foundation classes, such as the NSNumber class.
* Therefore, the property indicated by the right key path must hold an
* object that responds meaningfully to this message. The search
* ignores nil valued collection entries.

-- inputList of numbers return arrayWithMinString as NSString
on arrayWithMinString:anArray
return ((current application's NSArray's arrayWithArray:anArray)'s valueForKeyPath:"@min.self")
end arrayWithMinString:
(**
* valueForKeyPath: @sum.self
* When you specify the @sum operator, valueForKeyPath: reads the property
* specified by the right key path for each element of the collection,
* converts it to a double (substituting 0 for nil values), and computes
* the sum of these. It then returns the result stored in an NSNumber instance.
