You've used 'tee' without giving it any filenames, which is effectively the same as 'cat'. The one file it writes by default, stdout, you've redirected to a file, leaving nothing left for cut to get.
If you want tee to actually put the output into several files, don't redirect it, just tell which file you want
The -a is for append.

What I'd actually do, though?
Much more efficient, using nearly pure builtins except wc.

Tee(3pm) User Contributed Perl Documentation Tee(3pm)NAME
IO::Tee - Multiplex output to multiple output handles
SYNOPSIS
use IO::Tee;
$tee = IO::Tee->new($handle1, $handle2);
print $tee "foo", "bar";
my $input = <$tee>;
DESCRIPTION
"IO::Tee" objects can be used to multiplex input and output in two different ways. The first way is to multiplex output to zero or more
output handles. The "IO::Tee" constructor, given a list of output handles, returns a tied handle that can be written to. When written to
(using print or printf), the "IO::Tee" object multiplexes the output to the list of handles originally passed to the constructor. As a
shortcut, you can also directly pass a string or an array reference to the constructor, in which case "IO::File::new" is called for you
with the specified argument or arguments.
The second way is to multiplex input from one input handle to zero or more output handles as it is being read. The "IO::Tee" constructor,
given an input handle followed by a list of output handles, returns a tied handle that can be read from as well as written to. When
written to, the "IO::Tee" object multiplexes the output to all handles passed to the constructor, as described in the previous paragraph.
When read from, the "IO::Tee" object reads from the input handle given as the first argument to the "IO::Tee" constructor, then writes any
data read to the output handles given as the remaining arguments to the constructor.
The "IO::Tee" class supports certain "IO::Handle" and "IO::File" methods related to input and output. In particular, the following methods
will iterate themselves over all handles associated with the "IO::Tee" object, and return TRUE indicating success if and only if all
associated handles returned TRUE indicating success:
close
truncate
write
syswrite
format_write
formline
fcntl
ioctl
flush
clearerr
seek
The following methods perform input multiplexing as described above:
read
sysread
readline
getc
gets
eof
getline
getlines
The following methods can be used to set (but not retrieve) the current values of output-related state variables on all associated handles:
autoflush
output_field_separator
output_record_separator
format_page_number
format_lines_per_page
format_lines_left
format_name
format_top_name
format_line_break_characters
format_formfeed
The following methods are directly passed on to the input handle given as the first argument to the "IO::Tee" constructor:
input_record_separator
input_line_number
Note that the return value of input multiplexing methods (such as "print") is always the return value of the input action, not the return
value of subsequent output actions. In particular, no error is indicated by the return value if the input action itself succeeds but
subsequent output multiplexing fails.
EXAMPLE
use IO::Tee;
use IO::File;
my $tee = new IO::Tee(*STDOUT,
new IO::File(">tt1.out"), ">tt2.out");
print join(' ', $tee->handles), "
";
for (1..10) { print $tee $_, "
" }
for (1..10) { $tee->print($_, "
") }
$tee->flush;
$tee = new IO::Tee('</etc/passwd', *STDOUT);
my @lines = <$tee>;
print scalar(@lines);
