awk statement to find events from a specific date

I have a script which archives log file events which are 90-days old. Script works fine but I wanted some input on one aspect of this script. My nawk statement, bolded below, that removes events 90-days prior from today, I need it to find anything 90-days or older. The log file date pattern looks like this 03-29-2010

Code:

#!/bin/sh
LOG=tool.log
# Script will compress and archive tool log files older than 90-days
# Perl script to identify the date 90 days prior from today
  date=`perl <<'EOF'
  @T=localtime(time-86400 * 89);printf("%02d-%02d-%02d\n",$T[4]+1,$T[3],$T[5]+1900);
  EOF`
# Next statement will add logs 90-days old in command_archive.gz file
  nawk 'BEGIN {FS="\n"}{RS="#"}{ORS="#"}{if ($2 ~ /^'$date'/) print $0;}' $LOG > archive.temp
  gzip -c archive.temp >> command_archive.gz
# Next statement will remove logs 90-days old from the tool.log file
  nawk 'BEGIN {FS="\n"}{RS="#"}{ORS="#"}{if ($2 !~ /^'$date'/) print $0;}' $LOG > tmp_tool.log
  cp tmp_tool.log $LOG

update(n) Tcl Built-In Commands update(n) __________________________________________________________________________________________________________________________________________________ NAME
update - Process pending events and idle callbacks SYNOPSIS
update ?idletasks? _________________________________________________________________ DESCRIPTION
This command is used to bring the application ``up to date'' by entering the event loop repeatedly until all pending events (including idle callbacks) have been processed. If the idletasks keyword is specified as an argument to the command, then no new events or errors are processed; only idle callbacks are invoked. This causes operations that are normally deferred, such as display updates and window layout calculations, to be performed imme- diately. The update idletasks command is useful in scripts where changes have been made to the application's state and you want those changes to appear on the display immediately, rather than waiting for the script to complete. Most display updates are performed as idle callbacks, so update idletasks will cause them to run. However, there are some kinds of updates that only happen in response to events, such as those triggered by window size changes; these updates will not occur in update idletasks. The update command with no options is useful in scripts where you are performing a long-running computation but you still want the applica- tion to respond to events such as user interactions; if you occasionally call update then user input will be processed during the next call to update.
