imported images smaller than 9 pixels sq

I am not sure, but this might have to do with the minimum size that RR 
allows for objects.

See: -> Preferences -> Object sizes

Ther you can adjust the min value.

But you can still get the correct size of your tiny image with an 
almost identical
script:

...
unlock error dialogs
put the formattedwidth of last image into xwide
put the formattedheight of last image into hhigh
...

The formattedheidght/formattedwidth will give you the correct value 
(original size of the image)
and not the size of the image-object, which, in your case, will be min 
120*120...

Hope that helps...
