Tips on getting a proper match in iTunes Match

Question

I have a CD that was released last week - "Dio: This Is Your Life".  When I rip it, iTunes Match does its thing, and it matches only 3 of the 14 songs on the CD, the rest were uploaded.   The entire album/CD is in iTunes, so I know it should be matched.
To that, I tried a few tricks I've used in the past to get around that, and have it match everything.  Which was to tell iTunes to create a copy of the the CD in a different format (like 128k mp3), delete old files (plus from iCloud) and rescan.  That usually works.
That didn't this time - it showed me the same 3 songs, and the other 11 were instantly marked as uploaded - when they had not been.  So its obviously using the uploaded files I did the first time around.  I told you to delete them iTunes, so delete them! 
My question is this - how can I get it to REALLY delete the files from Apple's end, and not just tell me it does, so I can attempt a true rescan, and not just have it pick up the same results for the same album a few rips ago?   Additionally, it is picking up tweaks I made to the song info, I was trying to rip it with the default CD info (I assumed a delete including iCloud would delete all of it, but apparently not), but it doesn't seem to want to forget about my custom changes, either.  Subsequent rips from the CD automatically include the custom changes I made even after I deleted the files, quit iTunes, come back and attempted a re-rip.
So basically:
1) How can I get my iTunes library locally to forget about any custom song tweaks I made to a CD import for subsequent imports of the same CD?
2) Any other tips on attempting to get a better match with iTunes match besides the "make mp3 copy at other bitrate and attempt rescan" trick?

Jimzgoldfinch,
"Is your version the same as iTunes Store. Only 15 tracks on version in UK store. This could be a reason for non match!"
No, this is the US version on CD.  The physical media version has 14 songs.  The iTunes version has 15, but that should in theory be irrelevant, as it matches individual tracks, not entire albums as a collection.
"Usually reripping a CD on a different basis sometimes works especially when the album has only recently been added to store."
Agreed - I've done that already a few times.
"iTunes Match seems to remember version uploaded. Therefore if reripping on a different format does not work, you are running out of options. I don't think that there is anything else you can do."
Yeah, one of my main question is how do I get iTunes to "forget" what I've uploaded.  They ask you to "delete from iCloud", but that doesn't REALLY happen.  I had a theory that if you delete something, and don't try and re-access it in like a month, it'll really go away.  I can't imagine Apple storing all the uploaded files people upload and then "delete" indefinitely like that.
Michael Allbritton,
"Keep in mind that Apple does not promise you will get 100% matches for every track."
I'm aware of that.  I'm a day 1 iTunes Match customer.  I know the official line.  I also know the realities of what people have run into from reading the forums since then. 
"What format and bit rate did you rip the tracks from the CD? Lower bit rates will increase the chance of a track being "uploaded" rather than "matched." I suggest you delete the tracks ripped from the iTunes library and from the cloud and re-rip the tracks in at a higher bit rate. I recommend either ALAC or MP3 @ 320 Kbps."
The original rip attempt was in their "iTunes plus/AAC" format.  That's what I rip most everything with.  In the past, when I've tried this and didn't get matches, I'd go down and do a 128k mp3.  That usually works.  That didn't here, as it "remembered" my upload attempt from the iTunes Plus rip, and my "uploaded" status was instantly duplicated, with nothing actually uploaded on the second (and subsequent attempts).  I haven't tried going the other way and going to 320k mp3 before.
Does iTunes match "match" a wav rip?  Just curious - I've never ripped that way, but I have always wondered.
