in reply to alphabetize a hash ignoring upper/lower cases

vladb answer works fine, and I would like to add that if the code you posted is actually what you are doing instead of a simplified example, then you really don't need the keys of the hash and it can all be written as: 

my @mips = sort { lc($a) cmp lc($b) } values %mips;

    if you have a lot of elements doing the case conversion everytime you compare two elements this will be inefficent. i'd suggest: 
    my @imps =
  map { $_->[1] } 
    sort { $a->[0] cmp $b->[0] } 
      map { [ lc $_, $_ ] } 
        values %mips;
