[Plugin: FeedWordPress] Syndicated post order incorrect

I set up several RSS feeds in Feedwordpress and noticed that when the timestamp of items in the feeds are identical they are not imported in the correct order.

For example if I try to import the itunes top 25 songs from the itunes site using their rss feed http://itunes.apple.com/us/rss/topsongs/limit=25/xml

the items are not displayed in the correct order.

has anyone seen this problem and found a way to display in order?
