What is an intuitive interpretation of 100 in anchored max Diff (prob rescaled)?

It's the score equal to the utility of the threshold (anchor) item.  Or, in other words, if an item gets a 100, it's just as likely to be picked as the threshold.  

Let's say your threshold is the boundary between "buy" and "no buy."  An item getting a score of 100 has a 50% chance of "buy".  An item with a score higher than 100 is more likely to be rated as a "buy" than a "no buy."

Or, let's say that your threshold is the boundary between "important" and "not important".  An item with a score higher than 100 is more likely to be rated as important than not important.  An item with a score lower than 100 is more likely to be rated as not important rather than important.

Thank you for this answer. Is it then consisten to have 30 items and only 2 of them are below 100?
With anchored MaxDiff, it just depends on how your respondents evaluate the 30 items versus the anchor, and the text description and respondent instructions you use for the anchor.  It sounds like on average two of the thirty items were picked less often than the anchor.
