Hash sort again!!

[Anonymous Monk]

I realise I am stupid and shouldn't have been let loose on PERL in a million years but I need help!! Can anyone PLEASE help me with a hash sorting problem I am having?? I will be eternally grateful!!!!!!! I have successfully created a hash containing all the keys and values I want but wish to merely sort the keys into ascending numerical order. Am I doing something wrong with my hash assignment? I cannot quite see why it won't work See excerpt below

foreach $sentence(@sentences) { <BR>
    $total_sentence +=1; <BR>
    @words = split(/[^\w'a-zA-Z0-9_'-?]+/,$sentence); <BR>
    $Counter =0; <BR>
foreach $word(@words){ <BR>
    $Counter+=1; <BR>
    } <BR>
$sentence_count{($Counter)}=$sentence_count{($Counter)}+1;<BR>        
+                    
}
<BR>
sort {$a<=>$b} (keys (%sentence_count)); <BR>
print ("\nThere are a total of $total_sentence sentences in this text\
+n"); <BR>
while (($sentence_count,$word_count) = each(%sentence_count)) {  <BR>
    print ("\nThere are $sentence_count sentences of $word_count words
+\n"); <BR>
} <BR>
