I played with your original code a little and shamelessly stole the %COUNTS array from derekludwig. I came up with this without much regex...
Code:
#!/usr/local/bin/perl -w

use warnings;
use strict; 

# my @s_words = 0;
# my $fun_name = 0;
# my $file_name = 0;
# my $remove_hex = 0;
# my $word = 0;

my $filename = 'C:\data1.txt';
my @opcode_var = 0;
my $output_var = 0;
my %COUNTS = ();

open(my $FILE, '<', $filename) or die "Could not read from $filename";
my @lines = <$FILE>;
chop @lines;

foreach my $line(@lines) 
{
    if ($line =~ /0x*/)
    {
        chop ($line);
        @opcode_var = split(/ /,$line);
        
        if($opcode_var[2] =~ /0x*/)
        {
            $output_var = "$opcode_var[3] $opcode_var[4]";
        }
        else
        {
            if($opcode_var[1] =~ /0x*/)
            {
                if ($opcode_var[3] =~ /[;]+/)
                {
                    $output_var = "$opcode_var[2]";
                }
                else
                {
                    $output_var = "$opcode_var[2] $opcode_var[3]";
                }
            }
        }
    }
    print "$output_var\n";
    $COUNTS{$output_var}++;
}
print "\n";
while (my ($w, $n) = each %COUNTS)
{
    # printf STDERR "\(\%d\) \%s\n", $n, $w;
    printf STDERR "%-14s - occurred %-2d %s\n", $w, $n, $n < 2 ? "time" : "times";
}

close($FILE);

# eof #

# output
# ------
# BRA.l 0x60
# RETI
# MOV R0L,R0L
# RETI
# MOV R0L,R0L
#
# BRA.l 0x60     - occurred 1  time
# MOV R0L,R0L    - occurred 2  times
# RETI           - occurred 2  times
# or ...
# (1) BRA.l 0x60
# (2) MOV R0L,R0L
# (2) RETI

sestatus.conf

sestatus.conf(5)					    sestatus configuration file 					  sestatus.conf(5)

NAME

       sestatus.conf - The sestatus(8) configuration file.

DESCRIPTION

       The sestatus.conf file is used by the sestatus(8) command with the -v option to determine what file and process security contexts should be
       displayed.

       The fully qualified path name of the configuration file is:
	      /etc/sestatus.conf

       The file consists of two optional sections as described in the FILE FORMAT section. Whether these exist or not, the following  will  always
       be displayed:
	      The current process context
	      The init process context
	      The controlling terminal file context

FILE FORMAT

       The format consists of two optional sections as follows:
	      [files]
	      file_name
	      [file_name]
	      ...

	      [process]
	      executable_file_name
	      [executable_file_name]
	      ...

       Where:
	      [files]
		     The start of the file list block.
	      file_name
		     One  or  more  fully qualified file names, each on a new line will that will have its context displayed. If the file does not
		     exist, then it is ignored. If the file is a symbolic link, then sestatus -v will also display the target file context.

	      [process]
		     The start of the process list block.
	      executable_file_name
		     One or more fully qualified executable file names that should it be an active process, have its context displayed. Each entry
		     is on a new line.

EXAMPLE

       # /etc/sestatus.conf
       [files]
       /etc/passwd
       /etc/shadow
       /bin/bash
       /bin/login
       /lib/libc.so.6
       /lib/ld-linux.so.2
       /lib/ld.so.1

       [process]
       /sbin/mingetty
       /sbin/agetty
       /usr/sbin/sshd
