Tcl 8.5 vs 8.6 script throws error when run from python

My Python Script on Freebsd 9.2 is throwing error, while it worked fine on Freebsd8.2.

test.py 

import os
import subprocess
tclsh = '/usr/local/bin/tclsh'
process = subprocess.Popen([tclsh, 'run_tests.tcl'] )

test.tcl

proc sleep {N} {
    after [expr {int($N * 1000)}]
}

puts "--- Initializing----"

Throws the error 

File "run_tests.tcl", line 1
    proc sleep {N} {
         ^
SyntaxError: invalid syntax

So if I change the python script

-tclsh1 = '/usr/local/bin/tclsh'
+tclsh1 = '/usr/local/bin/tclsh8.5'

It works fine on Freebsd9.2.

However, if I execute command on command line it works fine too.

/usr/local/bin/tclsh  test.tcl

Error is thrown while running the command via python script on Freebsd 9.2 with tclsh1 = '/usr/local/bin/tclsh'

Does anyone know whats wrong here?

Thant's a python syntax error:

$ python
Python 2.7.6 (default, Mar 22 2014, 22:59:38) 
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> proc sleep {n} {
  File "<stdin>", line 1
    proc sleep {n} {
             ^
SyntaxError: invalid syntax

Are you sure /usr/local/bin/tclsh is a Tcl interpreter?

This line looks funny:

process = subprocess.Popen(['tclsh1', 'test.tcl'], bufsize=1, stdout=stdout, cwd=cwd)

If tclsh1 is a variable, why is it quoted?
