I can't really picture the first scene at all. Is Tyler "the man"? Could you capitalize the first time we see him? Is Tyler on stage? Where are the judges? On stage or in the audience? Is there an audience? Are there other actors, or is he doing a monologue? Is this a contest or a casting? Generally a director or casting director will cast actors, not "judges". And JUDGES should be capitalized if these are speaking roles.

He quickly closes a script - wait, when was he holding open a script? How and when did he get a script? Is CHARLES (capitalize the first time he appears on screen) the same as OLDER MAN, or are these two different people? Is OLDER GENTLEMAN another person or still the same guy? And Charles is later described as an "older fellow", could this maybe be condensed to CHARLES (60s)?

Always use a comma before and/or after the name when addressing someone directly in dialogue (even if the name isn't a proper name). Example sentence: "We're eating, Grandma!" vs. "We're eating Grandma!"

Lauren was sitting, eating dinner, and suddenly she's at Tyler's side picking up a bottle to examine it. When did she get up and walk over to him? Then she sets two plates on the table. Why? Didn't she already have a plate there? She sits down next to Tyler - when did he sit? She has a lot more food than he does - when did he get any food?

Sorry, I don't have time to go through the rest, but this has a lot of issues with clarity. I can't picture these scenes in my head because you're missing a lot of key information, lacking capitalization on character introductions, and not being consistent with how you refer to characters.

You could actually make it easier on yourself by adding less detail. If the action lines were simply "Tyler sets down bottles of booze on the counter and joins Lauren at the kitchen table for dinner." then it wouldn't be as confusing.
