One way is to read your file list into an array, then loop over each file performing the substitutions. UNTESTED: 
use strict;
use warnings;
use File::Copy;

my($replacePattern1) = "foo1";
my($searchPattern1) = "bar1";
my($replacePattern2) = "foo2";
my($searchPattern2) = "bar2";
my($replacePattern3) = "foo3";
my($searchPattern3) = "bar3";
my $pattern = 0;

my $list = 'list.txt';
open my $fh, '<', $list or die "can not open $list: $!";
my @files = <$fh>;
close $fh;
chomp @files;

for my $file (@files) {
    my $copy = "$file.bak";
    copy($file, $copy) or die "File $file cannot be copied: $!\n";
    open my $fhi, '<', $copy or die "can not open $copy: $!";
    open my $fho, '>', $file or die "can not open $file: $!";
    while (<$fhi>) {
        if (s/$searchPattern1/$replacePattern1/g) {
            $pattern = 1;
        }
        elsif (s/$searchPattern2/$replacePattern2/g) {
            $pattern = 2;
        }
        elsif (s/$searchPattern3/$replacePattern3/g) {
            $pattern = 3;
        }
        print $fho $_;
    }
    close $fho;
    close $fhi;
    unlink $copy;
}
