Since I sent the message, I learned that if you want to sort with
multiple criteria, the first argument should be an arrayref of closures.
So what I should have written is:
==> sort [ { .<score> } is descending, { .<word>.length }, { .<word> } ];
And it's easier to write if a simple numeric minus is used:
==> sort [ { -.<score> }, { .<word>.length }, { .<word> } ];
This makes sort sort by score first, but if two words score equally,
word length will become important (score with as few letters as
possible, because there's a greater chance of succeeding within the time
limit). If the lengths are also equal, it sorts alphabetically, so
that words beginning with the same letter are grouped together.
