this works for me (using 8.2).  on a 96-dpi screen,
the red box comes out smaller than the blue one:

from Tkinter import *

root = Tk()

print "original", root.tk.call("tk", "scaling")
Frame(root, bg="red", width="1c", height="1c").pack()

root.tk.call("tk", "scaling", "1.0")
print "new", root.tk.call("tk", "scaling")

Frame(root, bg="blue", width="1c", height="1c").pack()

mainloop()
