Welcome back! 103 is a good total score. Most schools that I looked at stated the minimum total score - if I remember correctly, the highest that I have seen is 100.
However, if you visit the TOEFL website, you can see the minimum score for each section that some schools set for graduate program. 19 would be a bit on the border line. E.g.
University of California - Berkeley
* Total Score: 68, with the following minimum section requirements
o Reading: 17
* Minimum Speaking score for appointment as a Graduate Student Instructor (TA): 26
Individual departments or programs may set higher minimum scores.
University of Texas - Austin
* Minimum Required Total Score: 79, with a preferred score of 21 for each section
I think it would be better to ask the schools directly. Another way is to address it in your essays, but I feel the space could be better used to talk about other things.
