You're missing a newline on the last line.
I think that you're mistaken—say (as opposed to print) provides it for me.
Furthermore, since you assume the list is constant, that can be simplified to
say for sort { $a <=> $b } 1..10;
Yes, you're right; I contemplated coming back and updating the node with that, but then I would have had to point out that sort { $a <=> $b } 1..10 could be replaced by just 1..10, and that seemed to be going too far. :-)
And if you wanted to show that stringification doesn't matter
That wasn't my goal, largely because I'm not sure what you mean. UPDATE: Because I was too busy writing one-liners to read the OP's actual question; sorry.

    Oops, right

    but then I would have had to point out that sort { $a <=> $b } 1..10 could be replaced by just 1..10,

    That wouldn't demo how to sort 10 after 9 rather than before 2.

    That wasn't my goal, largely because I'm not sure what you mean.

    The OP suspected that hashes keys are always strings and that stringification of the keys was the cause of his problem.

    Hash keys are always strings (except for magical hashes), but that's not the cause of his problem. Perl treats the number zero and the string zero identically (except for its bitwise operators).

    (I'm sure you know that. It's for the OP's benefit.)
