Alternatively,

nr=$(awk -e "/^[[:xdigit:]Xx]+[[:space:]]+${my_abis}/ {if (\$1 > max) max = \$1} \
             END {print max + 1}" "$in")

Matter of taste, of course - if that is ever get fed something so large that
use of sort + tail to find the maximum would be noticable, we are in a very
deep trouble for other reasons ;-)
