sort -r reverses the sense of all comparisons.
If you are on linux try msort - it allows you to invert (-i) the sense of the comparison on a field by field basis.
Otherwise you will have to write a sort in perl or C or python... whatever you like.

slamrg
slamrg.f(3) LAPACK slamrg.f(3)
NAME
slamrg.f -
SYNOPSIS
Functions/Subroutines
subroutine slamrg (N1, N2, A, STRD1, STRD2, INDEX)
SLAMRG creates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.
Function/Subroutine Documentation
subroutine slamrg (integerN1, integerN2, real, dimension( * )A, integerSTRD1, integerSTRD2, integer, dimension( * )INDEX)
SLAMRG creates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.
Purpose:
SLAMRG will create a permutation list which will merge the elements
of A (which is composed of two independently sorted sets) into a
single set which is sorted in ascending order.
Parameters:
N1
N1 is INTEGER
N2
N2 is INTEGER
These arguements contain the respective lengths of the two
sorted lists to be merged.
A
A is REAL array, dimension (N1+N2)
The first N1 elements of A contain a list of numbers which
are sorted in either ascending or descending order. Likewise
for the final N2 elements.
STRD1
STRD1 is INTEGER
STRD2
STRD2 is INTEGER
These are the strides to be taken through the array A.
Allowable strides are 1 and -1. They indicate whether a
subset of A is sorted in ascending (STRDx = 1) or descending
(STRDx = -1) order.
INDEX
INDEX is INTEGER array, dimension (N1+N2)
On exit this array will contain a permutation such that
if B( I ) = A( INDEX( I ) ) for I=1,N1+N2, then B will be
sorted in ascending order.
