Scholarship are different matters. Most likely, what your conselor didn't give you in time is not "scholarship offer", but "offer to apply for scholarships". But if you applied for those scholarships already and they were real scholarship offers, that lazy counselor might have broke the law by withholding your mail.
I was a National Merit Scholar a long time ago and if I recall, I received a letter from the organization directly. They should go back to that.
Edit: I’m talking literally 40 years ago >

I was as well, about 10 years ago. They sent the letter to my school. The only reason I knew anything about it was because another student who had a teacher as a parent. After a while the teacher went to the counselor to ask about results and found out she had the letters, and only then did she hand them out. 
I also got several big scholarships from one of my top 2 universities, but they sent those offers directly to my school instead of me. When I went to pick up my diploma after graduation, she handed me a massive package with all their scholarship offers. She just stuck them in my file and said nothing to me about them. I figured that school hadn't given me any and opted for the other university. She told me she didn't like delivering mail to students all the time so she just held on to them until they came to her office to get them. This was a small school, so it wasn't like that was a time consuming job to begin with, and I didn't even know they had any mail for me to pick up.
