I think the change has been made upstream. In fact, the behaviour
depends on your current locale. Try this:

fgrep "<Multi_key> <c> <o>" /usr/share/X11/locale/*/Compose

You will see that there are still locales where "Compose c o" maps to
"ǒ", in detail en_US.UTF-8 and fi_FI.UTF-8. In all other locales it is
mapped to "©".

Don't despair, there are still possibilities to enter it:

As unicode:
Press Ctrl-Shift-u followed by 01d2 and Space.

By creating your own compose mappings:
Create a file named ~/.XCompose by either copying one of
the /usr/share/X11/locale/*/Compose files or by editing it from scratch.
This way, you can create any mapping you want. You could also copy the
file from your Ubuntu 8.10 installation if you want it to be 100%
compatible.
