Strange language of football results

[pne]

Out of curiosity, I had a look at the football results in German and saw this for the game Portugal vs. England that took place on Thursday:

2:2 n.V. (1:1, 0:1), 6:5 i.E.

Now what the heck does that mean?

I assume the first bit is "half-time score was 0:1; score are 90 minutes was 1:1; score after extra time ["nach Verlängerung"] was 2:2" and that the extra time was necessary because the score was tied after the second half-time.

But what is the 6:5 and what does "i.E." mean?
