Well if there were no aliases in the numbers, you could always
sort the output numerically after the join if it was important.
However if you wanted to join "01" and "1" then your patch is required.
Are numeric aliases common enough to warrant this? I think so.

I'd use -g, --general-numeric to correspond with `sort`.
