looking for a smart approach to "sort" an array

[Mike Bonner]

It might be easiest to just have a single separate key that contains the
user sorted list, then use the data of that key itself to access the rest
of the array.

So if you have 5 keys, word1,word2,word3,word4,word5, but the user orders
them in reverse, your sorted words single key would contain
word5
word4
word3
word2
word1

Then to get everything back out in the right order one could use a repeat
for each line repeat loop on that key like so.

repeat for each line tKey in myArrayA["sortedWords"]
    -- do whatever with each one myArrayA[tKey].....
end repeat
