Yes, this was recently reported on the uClibc list.  And you are
right, this option is marked obsolete in sort from GNU coreutils.
Quoting the sort info page:

   On older systems, `sort' supports an obsolete origin-zero
   syntax `+POS1 [-POS2]' for specifying sort keys.  POSIX
   1003.1-2001 (*note Standards conformance::) does not allow
   this; use `-k' instead.

So I think rather than changing busybox, in this case ncurses
should be fixed to instead use the '-k' option.

The -n option for numeric sort seems to be properly supported
and doesn't take an argument from my reading of the standards,
