in reply to print +split

The + is there to keep print from thinking those parentheses contain its argument. You are missing the $ on diff in your if. The if doesn't match because the line does not start with digits. 
use strict;

would have helped you some. Some judicious print statements would also be enlightening. The code is getting pretty bletcherous. Did you copy some of these constructs?

I've updated it just enough that it runs and you can see what you've got. I don't know where you want to take it from here. 

use strict;
use warnings;

my $dev  = qw/original1/;
my $dev1 = qw/clinical1/;
my $diff=0;
#        open (FOO, "samcmd a $dev 2>\&1 |" ) || die 
# "unable to open pipe... Broken? $!";
        while (<DATA>) {
             if (/regular files|archdone files/) {
                local $, = "\n";
                #s/^\w+(\s+)\w+(\s+)// && s/,//,;
                s/,//, print +(split)[2], $,;
                if (/^\d+/) {
                        $diff -=$1; ##--## 62622-62535
                }
                else {
                    print "$_ does not start with digits.\n";
                }
            }
        }
        print "Difference is: $diff\n";

#close (FOO) or warn "unable to close file $!";

    yes Roy, thanks but I intended to paste everything including use strict, but forgot. The missing $ was a mistake...sorry I have the same code and it is not subtracting the two values 62622 and 62535.

      Your code wasn't performing a subtraction. Also, as Roy mentioned the /^\d+/ wasn't matching.

        Chas.... I understand now... my bad. Anyway it is printing the two elements of not computing the difference.

64696

64684

Difference is: 64696 - 64684
