If you're done with your classes for this semester and you aren't taking classes over the summer, you might as well send the transcript now. As @Pacifico said, you can update them after your fall grades come in.
I would score whatever is on the scan-tron, as that is what will happen on test day. As someone who had an error on test day, they can be devastating, as you also know. If you are double checking, where are you making your errors, what section?
I would say score the test twice, once with the error and once without. That way you see what you could have gotten without the error and also have a good reflection of your actual understanding.
I was just clarifying June 30th as Thursday haha @Sheri123...LSAC was helping me out with transcript stuff and she said scores would be released June 30th.
