Matching set of paragraph tags with string inside.by the_0ne (Pilgrim)

the_0ne has asked for the wisdom of the Perl Monks concerning the following question:
I just can't seem to get these look-ahead/look-behind assertions down pat like some of you. I have this code...
What I want here is to say only match the set of paragraph markers with the actual string [tab] inside.
Notice the first one DOES match, however, since I am using .*? the first para marker will match and then the .* will take over and match all the way to the close para marker. I want the first para marker to fail because there is no [tab] inside the paragraph markers.
The second one is a look-ahead, but notice the [tab] would have to be immediately after the para marker. I can't figure out how to tell it the possibility of some text, then the [tab], then the possibility of more text.
Thanks for any assistance you may provide...
