Use quotes

Code:
a='03'

or using Korn shell print it out in the correct format
Code:
a=3
printf '%02d\n' ${a}

What shell are you using? It must be broken to do that. My version of ksh does
Code:
#
# a=03
# echo ${a}
03
# ((a=03))
# echo ${a}
3
#

In the arithmetic assignment the leading 0 means the number is octal.
Code:
# ((a=010))
# ((a=a-1))
# echo ${a}
7
#

There is not too much you can do with a broken shell. Can you try a better shell?
