I wouldn't worry about it either.
When I put my GMAT scores into my application I accidentally mixed up my Quant and Verbal scores.
I noticed it in a post-submittal review and emailed NYU about it. I knew they'd see the problem because the scores I put on my app would not match the scores that they received from the testing service.
I fretted about the mistake for a while, like you are, but in the end, they still accepted me.
