iPhoto not syncing pictures in correct order...

I have an iPhone 4S, I have recently been on holiday and have took lots of pictures and videos on my iPhone. When getting home I have synced my iPhone to my MacBook Air.
I imported all the photo's into iPhoto fine and created 1 event for all the photos.

I then deleted all photos from my phone but wanted to re-sync them using iTunes. However when selecting that event in iTunes, all of the photos arent in the same order as they are in iPhoto, some of the photos & Videos are duplicated on my iPhone. But in iPhoto they are fine.

Can anybody help or suggest a way to make the event in my photos on my iPhone the same as iPhoto.
