On the same lines of your last post, just a few recommendations...

The problem I think is that, I'm not invoking a.sh, but sourcing it inside b.sh
Yes, that's the problem, you need to invoke a.sh script. Sourcing it, will cause it to get executed in the place of the current shell ( b.sh shell/environment), so every command of a.sh will get place in the b.sh shell /environment.
Secondly, in your situation you don't need export in a.sh. That will export the value of the variable A_DIR in the subshells of a.sh ( ex. if you invoke other scripts within a.sh, etc ... ). So to access the value of A_DIR in the outer script b.sh for further processing, one way of doing it, is through invoking a.sh and put the value of A_DIR in a temporary file inside a.sh :

a.sh script :

Code:
#!/bin/sh
IN_DIR=`dirname $0`

CUR_DIR=`pwd`
cd $IN_DIR
A_DIR=`pwd`
cd $CUR_DIR

echo $A_DIR > /hello/by/temp_file

and b.sh script :

Code:
#!/bin/sh

/one/two/a.sh
my_dir=`cat /hello/by/temp_file`

#To see the result
echo " This is A_DIR " $my_dir

# If you don't need the temp_file 
rm /hello/by/temp_file

Hope this helps.

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
