Code:

#         printf "%.2d \n" $CURRENT
         printf "%.2d \n" $CURRENT >>count.txt
         lv_val=$(printf "%.2d" $CURRENT)

The %.2d says to format for two digits, thus can allocate from device _02 to _99. If you want to be able to go past this, simply change the script to %.3d before you execute. (Your example seemed to skip over the possibility of a _01 device.)
However, I would find it unusual to think you would be configuring more than 99 devices.

Before implementing this or any other suggestions, strongly recommend 'trial runs' where you do not execute the commands, but display/print the commands you are about to run.

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
