This will do it, starting the numbering at 0:
set myArcName_[*].tar.gz myArcName_*.tar.gz
if test "$1" = 'myArcName_[*].tar.gz'
   test "$2" = 'myArcName_*.tar.gz'
  then shift
fi
newname=myArcName_$#.tar.gz

If you can assume there are already some files present, numbered from
0, then you can simplify it:
set myArcName_*.tar.gz
newname=myArcName_$#.tar.gz
