I actually prefer it the way it is. It should be fairly obvious to non-Perl programmers what is going on here, and slamming everything into one line will certainly make some ears blead. However, by grouping things together, you can have a little of both worlds: 
$report =~ tr/0-9//d;  # numbers
$report =~ tr/-_.//d;  # underscores, dashes, and periods
$report =~ s/crs//ig;  # crs, lower or upper
$report =~ s/html//g;  # filter out the phrase 'html'

Update
Nice catch merlyn. I'll leave that comment untouched, as i had originally tried /_-./ before posting. I should add that i rarely use comments like that anymore as they are maintenance nuisances, IMHO.
