I have uploaded new versions of the HSK 2012/2013 lists, ordered by frequency. There are links to these new lists on the word lists page. This is a pretty good ordering to learn the words in each list; from the most to least frequent. The only change to the frequency odering is when a multi-character word would be learned before the characters within that word - in that case the characters are moved in front of the word.

If you use Pleco's flashcards to study for the HSK, you should update to the latest words lists. Uploaded to the Word Lists page, and to Pleco's Forums.

I have uploaded some HSK 2012 word lists. There are versions with just simplified characters, and others with simplified, traditional, pinyin, and definitions which might be handy for anyone but are specially formatted for use with the iPhone App Hanzi StickyStudy.  There is also a list of example sentences that illustrate grammar points, taken from the HSK information published by Hanban. You can download all of the lists here.
