I think you've misunderstand Simon's suggestion, which was:

<p>Rating: <img src=1 alt=3/5><img src=1 alt><img src=1 alt><img
    src=0 alt><img src=0 alt></p>

Note /all/ the img elements have alt attributes, the point is the 
alternative text for the group is expressed by the first alt attribute. 
It's thus actually the same as the fallback you propose:
