These are the first three posts I see:
First, at the top: "Marvelous in My Monday 3/4" - published Mar 4, 2013 @ 5:11
Second, just below the above: "I made the switch!" - published Mar 3, 2013 @ 18:17
Third: "The switcheroo + Week of 3/4-3/10" - published Mar 3, 2013 @ 13:30
The display you're seeing is to be expected, because everything is in reverse chronological order, with the most recent posts displayed first.
If you're trying to switch the order of "I made the switch!" and "The switcheroo + Week of 3/4-3/10" you can click the Edit link next to either one of them, and adjust the publication time to change the order.
For example, on the post "The switcheroo + Week of 3/4-3/10" you will see this:
Click Edit, change the time to make it later than 18:17 on March 3, click OK, and click Update.
The positions of the two March 3 posts should now be reversed.
