Created two plugins instead of updating

I was given the task of updating our WordPress plugin (IDXPro) – the persons who did the original development and updates being long gone. I followed the instructions, I thought, but there are now two versions of our plugin there, the first one being the original, which is out of date.
I think that the problem is that I re-submitted the plugin through the form here. Then I did the repository checkout and checkin, and tagged with version 1.3.. I have this situation:

http://wordpress.org/plugins/search.php?q=idxpro

I am completely new to subversion, so it’s entirely possible that I messed it up there. What I would like to do is either have the 1.2 version hidden (or at least come up second), or re-do it so that I update that version, and get rid of the one that I checked in today… Any thoughts?

Thanks so much,
Andy Wallace
