That is admittedly reinventing the
wheel, but the existing wheels aren't entirely round.  You still
have to dynamically allocate the array of ints, assuming you need
to store all of them rather than processing each value as it's read.

OK, a bit of a challenge for my scripting language. I managed this first:
   nums := sort(mapv(toval, splitstring(readstrfile("data.txt"))))
It needed a change to 'splitstring' to allow a default separator consisting of white space of any length. And a one-line helper function 'toval' since the usual candidates, special built-ins, were not valid for 'mapv'.
It also works like this:
   nums := readstrfile("data.txt") -> splitstring -> mapv(toval) -> sort
But only by chance since the 'piped' argument is the last one of multi-parameter functions, rather than the first.
