I get a different error, "can't find object", which I would expected
because "selected" is an object property, not a global property.
To deselect all objects use "select empty", or loop through all controls
with something like:
repeat with i = 1 to the number of controls
set the selected of control i to false
"select empty" will probably be much faster, and certainly simpler to type.

This one's a gray area.
The selectedObject resolves to an object reference, so as written it
seems the engine is attempting to get the number of lines in the object
itself (the text property) rather than the object reference string.
To force evaluation to operate on the list of objects rather than the
object itself, using parentheses seems to do the trick:
put the number of lines of (the selectedObject)
