Hi.

Recent versions of GNU ls have an ability like this. Using your list of version strings as a-v.tar.gz
Code:
#!/usr/bin/env bash

# @(#) s1	Demonstrate sort by version, GNU ls.

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
edges() { local _f _n _l;: ${1?"edges: need file"}; _f=$1;_l=$(wc -l $_f);
  head -${_n:=3} $_f ; pe "--- ( $_l: lines total )" ; tail -$_n $_f ; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C ls align

pl " Results:"
( pe "Plain	Version"
paste <( ls -1 a* ) <( ls -1v a* )
) |
align

exit 0

producing:
Code:
% ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0.8 (lenny) 
bash GNU bash 3.2.39
ls (GNU coreutils) 6.10
align 1.7.0

-----
 Results:
Plain			Version
a-0.1.0.tar.gz		a-0.1.0.tar.gz
a-0.1.tar.gz		a-0.1.tar.gz
a-0.10.0.tar.gz		a-0.2.0.tar.gz
a-0.10.3.tar.gz		a-0.2.3.tar.gz
a-0.10.tar.gz		a-0.2.tar.gz
a-0.100.0.tar.gz	a-0.3.0.tar.gz
a-0.100.tar.gz		a-0.3.tar.gz
a-0.11.0.tar.gz		a-0.10.0.tar.gz
a-0.11.tar.gz		a-0.10.3.tar.gz
a-0.2.0.tar.gz		a-0.10.tar.gz
a-0.2.3.tar.gz		a-0.11.0.tar.gz
a-0.2.tar.gz		a-0.11.tar.gz
a-0.3.0.tar.gz		a-0.100.0.tar.gz
a-0.3.tar.gz		a-0.100.tar.gz

It appears best to have a consistent number of sub-versions in the version strings.

Best wishes ... cheers, drl

   Functions/Subroutines
       subroutine slasrt (ID, N, D, INFO)
	   SLASRT sorts numbers in increasing or decreasing order.

Function/Subroutine Documentation
   subroutine slasrt (characterID, integerN, real, dimension( * )D, integerINFO)
       SLASRT sorts numbers in increasing or decreasing order.

       Purpose:

	    Sort the numbers in D in increasing order (if ID = 'I') or
	    in decreasing order (if ID = 'D' ).

	    Use Quick Sort, reverting to Insertion sort on arrays of
	    size <= 20. Dimension of STACK limits N to about 2**32.

       Parameters:
	   ID

		     ID is CHARACTER*1
		     = 'I': sort D in increasing order;
		     = 'D': sort D in decreasing order.

	   N

		     N is INTEGER
		     The length of the array D.

	   D

		     D is REAL array, dimension (N)
		     On entry, the array to be sorted.
		     On exit, D has been sorted into increasing order
		     (D(1) <= ... <= D(N) ) or into decreasing order
		     (D(1) >= ... >= D(N) ), depending on ID.

	   INFO

		     INFO is INTEGER
		     = 0:  successful exit
		     < 0:  if INFO = -i, the i-th argument had an illegal value
