Takers at 32% means that out of all Takers discs sold, 32% were on Blu-ray (and so 68% were on DVD). Since Blu-ray+DVD combos are counted as Blu-ray, and there were no DVD versions of Buried, it's Blu-ray market share is 100% (in other words, the Buried DVD version accounted for 0% of all Buried disc sales, since it did not exist).

As for why a 7th placed Blu-ray only release did not make the top 20 combined list, it requires a bit of maths to figure it out using the "Top 20 Blu-ray" index figures and the market share data, and it's easier if we convert everything to real numbers first.
Buried had a Blu-ray sales index of 26.11, while The Expendables (last place on the combined top 20 list) had a Blu-ray sales index of 14.07. Times both numbers by 100, we get 2611 and 1407 - let's pretend these are the actual number of Blu-ray units sold for each movie.
We know that The Expendables' Blu-ray market share was 43%. This means the total units sold figure for The Expendables, including both DVD and Blu-ray units, becomes 3272 (1407 out of 3272 is 43%).
Since all of Buried sales were of the combo version and there were no DVD-only versions, the Buried "sales figure" of 2611 *is* the total units sold figure for this movie, and since it's below the total units sold figure of The Expendables (3272), the 20th placed title on the combined list, this is why Buried did not make the combined top 20 list.
