The command below does not use mp3info as I don't have it installed, but it 
does the job for me:

file "dirname"/* | awk 'BEGIN {total=bad=0} /contains: MPEG ADTS, layer III/ { 
x=match($0, "^([^:]+):.*, ([0-9]+) kbps,", a); total++; if(x>0 && a[2]<192) 
{bad++}} END {print total, bad}'

Replace dirname with the name of the directory you want to scan (keep the 
quotes around the name so that special characters don't cause a problem).

One more thing: I assumed by "number of files in a directory" you meant 
"number of mp3 files in a directory".
