That sort of checking is going to be impossible to do 100% reliably. In the instant after checking a file, the other program may move it anyway.
I'd try to prevent the two code segments from running simultaneously instead. The mkfifo command will fail if the file already exists, so you can use it to check who gets there first:
There's many other problems with your script as well:
Useless Use of Cat -- the shell is quite capable of reading files by itself. Useless Use of Backticks -- using backticks on open-ended lists is an invitation to disaster. Useless Use of ls * Useless Use of grep | awk -- awk is an entire programming language which can do much more than 'print $5'. If you're using it, you might as well replace the pipe chain with it.
I'd rewrite it as so:
It may be possible to replace your entire loop with a single ls and a > < string comparison, if the date is in the filename itself.

dh_installdeb
DH_INSTALLDEB(1) Debhelper DH_INSTALLDEB(1)NAME
dh_installdeb - install files into the DEBIAN directory
SYNOPSIS
dh_installdeb [debhelperoptions]
DESCRIPTION
dh_installdeb is a debhelper program that is responsible for installing files into the DEBIAN directories in package build directories with
the correct permissions.
FILES
package.postinst
package.preinst
package.postrm
package.prerm
These maintainer scripts are installed into the DEBIAN directory.
Inside the scripts, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands.
package.triggers
package.shlibs
These control files are installed into the DEBIAN directory.
Note that package.shlibs is only installed in compat level 9 and earlier. In compat 10, please use dh_makeshlibs(1).
package.conffiles
This control file will be installed into the DEBIAN directory.
In v3 compatibility mode and higher, all files in the etc/ directory in a package will automatically be flagged as conffiles by this
program, so there is no need to list them manually here.
package.maintscript
Lines in this file correspond to dpkg-maintscript-helper(1) commands and parameters. However, the "maint-script-parameters" should not
be included as debhelper will add those automatically.
Example:
# Correct
rm_conffile /etc/obsolete.conf 0.2~ foo
# INCORRECT
rm_conffile /etc/obsolete.conf 0.2~ foo -- "$@"
In compat 10 or later, any shell metacharacters will be escaped, so arbitrary shell code cannot be inserted here. For example, a line
such as "mv_conffile /etc/oldconffile /etc/newconffile" will insert maintainer script snippets into all maintainer scripts sufficient
to move that conffile.
It was also the intention to escape shell metacharacters in previous compat levels. However, it did not work properly and as such it
was possible to embed arbitrary shell code in earlier compat levels.
The dh_installdeb tool will do some basic validation of some of the commands listed in this file to catch common mistakes. The
validation is enabled as a warning since compat 10 and as a hard error in compat 12.
