How about (see below) ... would that work with "-u"?
"`-k POS1[,POS2]'
`--key=POS1[,POS2]'
Specify a sort field that consists of the part of the line between
POS1 and POS2 (or the end of the line, if POS2 is omitted),
_inclusive_.
Each POS has the form `F[.C][OPTS]', where F is the number of the
field to use, and C is the number of the first character from the
beginning of the field. Fields and character positions are
numbered starting with 1; a character position of zero in POS2
indicates the field's last character. If `.C' is omitted from
POS1, it defaults to 1 (the beginning of the field); if omitted
from POS2, it defaults to 0 (the end of the field). OPTS are
ordering options, allowing individual keys to be sorted according
to different rules; see below for details. Keys can span multiple
fields.
Example: To sort on the second field, use `--key=2,2' (`-k 2,2').
See below for more notes on keys and more examples. See also the
`--debug' option to help determine the part of the line being used
in the sort.
