Think about it this way:

Similarly to what Super Saiyan 7 Somebody mentioned, you have Edit A as failed reverting. You have Edit B, which is the vandalism. You're trying to "undo" Edit B even though Edit A is still in existence. True, you could undo each one of the edits individually. However, the best solution is go to Edit C, fill in a custom edit summary, preview and publish.

Instructions (with Banana Farm as the example page): Also, a more efficient way of reverting: — Thread:25579
 * 1) On the page history, click the prev link to compare the revision (on the same line as that prev link) with the previous version (e.g. leading you to this page.)
 * 2) Click the edit button on the older revision.
 * 3) Fill in an edit summary (e.g. reverted vandalism)
 * 4) Preview to check it's the right version
 * 5) Publish :)
