There is no concept of "re-scanning" an already scanned item . Not that I've ever been able to find. So you're stuck with it, unless you delete it out of your collection, add the file back manually, and rescan. However, I tried playing with this a bit this morning, an found some interesting things.
1) The track "Let There Be Rock" from the album of the same name. I have that as an old 192k mp3 from a long time ago. I deleted that out, and picked the "Delete from iCloud" option. Put it back, re-ran the scan, and it told me the file was "uploaded". It apparently found my old upload during the scan and matched it, as it did NOT re-upload the file during my scan.
2) I deleted my entire "High Voltage" album out of iTunes, picking "Delete from iCloud". Then I re-ripped the CD fresh, and re-ran the iTunes match. It then proceeded to upload the nine tracks it ripped. That was annoying.
It would appear from my limited testing this morning, that whatever iTunes/Apple is using as the match source for these albums doesn't exactly match my local copy, so it'll get uploaded.
I AM HOPING it's related to the iTunes in the Cloud outage from earlier this morning. I would hate to have all of my existing AC/DC CD's not be matched.

There is not automatic rescan and even if you delete the original uploaded tracks and rerun match, I have found that the tracks are upload immediately without going through the normal upload process I.e. match finds your original upload even though you have deleted them from the cloud. Don't known if or when they are really delete.
However, I have found that if you convert the track from mp3 to AAC or vice versa, you have a chance of getting the songs match. Once you have converted the tracks, delete the originals from your library then select and ctrl click required tracks then select add to cloud. Match will rerun and if lucky tracks will now be matched. No guarantee especially if the iTunes Store has remastered versions.
