Anyways i went with the below approach and the process was terminating if sort is not working

sort -k 1.10,1.20n -o $inputfile $outputfile 2>> error_log
pgmcc=$?

if [[ $pgmcc != 0 ]]
then
echo "FATAL ERROR, TERMINATING NOW"
fi

In this case i'm just getting the error written in error_log as sort: A write error occured while sorting.

But i want to capture error which comes on the console something like below:

vxfs: msgcnt 5980 mesg 001: V-2-1: vx_nospace - /dev/vx/dsk/drd_rootdg/tmpvol file system full (2 block extent)

Is there a way if i can achieve the above...??
No. The vxfs error message is not being written by sort; it is a diagnostic message being written to the console by the operating system. The 2>>errlog will append diagnostics written by sort to errlog, but can't capture messages written to the terminal by the operating system nor by unrelated processes.

Your system probably has a log file where error messages written to the console are saved (but if the filesystem where the log files would be written is full, the message might only appear on the screen). Where those log files are kept is system specific.

WRAP-AND-SORT(1)					      General Commands Manual						  WRAP-AND-SORT(1)

NAME
wrap-and-sort - wrap long lines and sort items in Debian packaging files SYNOPSIS
wrap-and-sort [options] DESCRIPTION
wrap-and-sort wraps the package lists in Debian control files. By default the lists will only split into multiple lines if the entries are longer than 80 characters. wrap-and-sort sorts the package lists in Debian control files and all .install files. Beside that wrap-and-sort removes trailing spaces in these files. This script should be run in the root of a Debian package tree. It searches for control, control.in, copyright, copyright.in, install, and *.install in the debian directory. OPTIONS
-h, --help Show this help message and exit. -a, --wrap-always Wrap all package lists in the Debian control file even if the entries are shorter than 80 characters and could fit in one line line. -s, --short-indent Only indent wrapped lines by one space (default is in-line with the field name). -b, --sort-binary-packages Sort binary package paragraphs by name. -k, --keep-first When sorting binary package paragraphs, leave the first one at the top. Unqualified debhelper(7) configuration files are applied to the first package. -n, --no-cleanup Do not remove trailing whitespaces. -d path, --debian-directory=path Location of the debian directory (default: ./debian). -f file, --file=file Wrap and sort only the specified file. You can specify this parameter multiple times. All supported files will be processed if no files are specified. -v, --verbose Print all files that are touched. AUTHORS
wrap-and-sort and this manpage have been written by Benjamin Drung <bdrung@debian.org>. Both are released under the ISC license. DEBIAN
