Sort decimal integers numerically; if the first differing
characters of two test strings are not digits, sorting
is lexical. Integers with more initial zeroes
are sorted before those with fewer or none. Hence the array `tt(foo1 foo02
is lexical. `tt(+)' and `tt(-)' are not treated specially; they are treated as
any other non-digit. Integers with more initial zeroes
are sorted before those with fewer or none. Hence the array `tt(foo+24 foo1 foo02
foo2 foo3 foo20 foo23)' is sorted into the order shown.
May be combined with `tt(i)' or `tt(O)'.

item(tt(-))(
As tt(n), but a leading minus sign indicates a negative decimal
integer. A `tt(-)' not followed by an integer does not trigger
integer. A leading minus sign not followed by an integer does not trigger
numeric sorting.
Note that `tt(+)' signs are not handled specially (this may change in the
future).

Sort the resulting words in ascending order; if this appears on its
