How's this? You'll still need logic to decide what to remove.
ls -lt | awk '{ print $9 }' | cut -d_ -f1 | sort | uniq | while read prefix x
do
ls -t ${prefix}* | sort -r | tail +3
done

dh_di_numbers
DH_DI_NUMBERS(1) Debhelper DH_DI_NUMBERS(1)
NAME
dh_di_numbers - install numbered scripts into package build directories
SYNOPSIS
dh_di_numbers [debhelper options] [dir [...] dest]
DESCRIPTION
dh_di_numbers is a debhelper program that installs directories of numbered scripts into package build directories.
Within each directory, there should be a "_numbers" file in which each line contains at least two space-separated fields. The first field
in each line is a two-digit number, which will be prefixed to the entry name to provide ordering within the directory; the second is the
entry name, which must correspond to a file or directory alongside the "_numbers" file; and the third field, if present, is another two-
digit number which identifies another entry with the same entry name to which this entry should be a symlink.
Any additional directory names specified as parameters will be installed in the package build directory of the first package dh_di_numbers
is told to act on. By default, this is the first binary package in debian/control, but if you use -p, -i, or -a flags, it will be the first
package specified by those flags.
FILES
debian/package.di-numbers
List the directories to install into each package and the directory they should be installed to. The format is a set of lines, where
each line lists a directory or directories to install, and at the end of the line tells the directory they should be installed in. The
name of the directories to install should be given relative to the current directory, while the installation directory is given
relative to the package build directory. You may use wildcards in the names of the files to install (in v3 mode and above).
OPTIONS
dir [...] dest
Lists directories to install and where to install them to. The files will be installed into the first package dh_di_numbers acts on.
SEE ALSO
debhelper(7)
This program is a part of dh-di.
