bug with navigating tables in iTunes

Ever since I updated to iTunes 11 in November, I noticed a bug when browsing the top 200 songs in a table with voiceover. After selecting the, "Top singles" link on the iTunes store homepage, a table with the top 200 songs would load. When I try to navigate it with voiceover, it first says, "Table 6 columns, seventy [or so] rows." When I passed that number on the table with the up and down arrow keys, it would jump randomly, for example, 84, move down one to 91. I tried calling applecare about this when iTunes 11 was initially released, but the representative didn't seem to no what I was talking about by "top singles" link. In voiceover, it is spoken as "heading level 3 link, top singles." When you select or click it, it will load the table and that's where I run into the bug. I thought I'd wait for some updates, but with the release of two updates already with no fix in site, I thought I would ask on this form.
