'&&' is probably the wrong operator here.  Use 'and' instead

if 	(($start_pub_year ge $yr and $end_pub_year le $yr) and
	 ($start_pub_mon ge $mo and $end_pub_mon le $mo) and
	 ($start_pub_day ge $day and $end_pub_day le $day))

I don't remember whether 'ge' is the right choice instead of '>=' 
either.  I wouldn't use it myself, but that doesn't mean it's wrong.

And as Christian Huldt said, you need to make sure you know what 
you're comparing.
