That precise syntax never worked.
However, syntax like this used to be the norm:
sort +3 -5 myfile
Now, while that is still supported, you usually have to
go through hoops (set the _POSIX2_VERSION envvar to some small number)
to make it work. For details, read "info coreutils standards"
and then the section on sort.
