Sed or Awk usage to rename string

I have gotten myself totally lost trying to sort this out and just need some help please..

I will have a multiple directories using the following naming convention with an undetermined number of files in each directory.

9780743582094_05of5_Accountable.wav

I need to batch rename all files grabbing the two digit number after the first underscore, and appending it to the end of the file name,with a preceding hyphen, before the extension.

The example: 9780743582094_05of5_Accountable.wav

Would become

9780743582094_05of5_Accountable-05.wav

I know sed or awk could work but I have not been using Linux/Unix for some time and really have burned out trying to remember this. Please show me the way with an explanation. I am using Ubuntu 10.04 and have the rename command available to me.

For those who are going to insist to see some effort on my part, sadly this is all I've got:

Code:

for i in `ls|grep -o '_[00-99].'|tr '_' '-'`; do echo $i;done

The reason i am doing this is to try and use a script that I found to batch convert wav files to .m4b audiobook format, but I first must convert to mp3. If anyone has a better suggestion to accomplish this, I would also love to hear about that. But first, I really need an answer to this sed issue because it is upsetting me.

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.
