I tried out kyles suggestion of putting a '\' before the $processor but got the error message

 Processor is SCALAR(0x15f1a8) and qmgr is QM_P266 
 In bind_cpu_solaris , Processor is SCALAR(0x15f1a8) 
 In for loop ...
 In Next Loop ...
/usr/sbin/pbind: must specify at least one pid

The processor variable is populated in one other location where it looks for pid's of other processes already bound to a specific processor and tries to bind to the same (i.e populate $processor with the same proocessor id). the code is like the below:

sub get_cpu_used_by_other_processes
{
        my $other_process = shift;
        my $proc_id = locate_process_id( $other_proc );
        my $processor = undef;
        my $pid = undef;

        my @cmd_output = `$os_command_table{$^O}{pbind} -q 2>/dev/null
+`;
        die "ERROR:failed to retrieve the bound processors\n" unless (
+ $? == 0 );
        ##### increase the weight of processors based on used or not #
+####
        foreach ( keys %{$proc_id} )
        {
                $pid = $$proc_id{$_};
                next unless defined $pid;
                foreach ( @cmd_output )
                {
                        $processor = $1, return \$processor if /proces
+s\s+id\s+${pid}\s*:\s*(\d+)
$/;
                }
        }
}
