How can I select same size object in Illustrator? Is there an adobescript

How can I select same size object in Illustrator? Is there an adobe script
suited for that? I would like to select an object and then select same
object size all over my artboard? I've got a document with tones of
squares in five different size. They have all the same color, blend and
stroke, and I'm supposed to change the color of all five different sizes.
That would be a pain in the neck without a script! I've found this script,
but it was made for CS4 and it works only for path size.
