The +POS1 -POS2 syntax for specifying sort keys was (from memory) marked as obsolescent in IEEE Std. 1003.2-1992 and removed (and disallowed) in 1003.1-2001. Many applications (like lorder) use the old syntax, so by default GNU sort does not conform to the 2001 standard and accepts the old syntax. If you set _POSIX2_VERSION=200112 in the environment before running GNU sort, it will try to conform to the newer standard and treat "+pos" as a filename instead of a sort key. The version of sort in -stable was written before the 2001 standard and doesn't disable the obsolescent sort key syntax. So the only explanation that I can think of is that you've got _POSIX2_VERSION set in the environment: $ _POSIX2_VERSION=200112 sort +1 sort: open failed: +1: No such file or directory lorder should probably get changed to use the new syntax some time too.
