I appreciate the note in the reference, that does explain it better, however, call me a skeptic, but I'm still not convinced of her age for a couple of reasons.
 * I can fully get behind Isabella being a tween, which a quick google search tells me is 8-12. That's cool. I see where it's coming from with her reading Tween Bleep magazine in Cheer Up Candace. While it is true you can read above or below your age demographic, I think that's fine.
 * In Act Your Age the only time the word "eleven" shows up in is when Buford says "Oh, come on! It was so obvious! She came over to your house every day for eleven years just to see what you were doin'!" But we see in What Might Have Been that Isabella came to Phineas's yard both before and after the main summer, so I don't think it's fair to say she is 11/12/13 during the series
 * Finally, I just don't think it make sense canonically for Isabella to be ~3 years older than all her friends, or to start college at age 21/22/23 when the typical age to start college in the US is 18/19
