I couldn't find a function for counting the values with case-insensitive matching, so I wrote a quick and dirty solution myself:

This prints:

Array
[
    [J. Karjalainen] => 3
    [60] => 2
    [j. karjalainen] => 1
    [Fastway] => 2
    [FASTWAY] => 1
    [fastway] => 1
    [YUP] => 1
]
Array
[
    [J. Karjalainen] => 4
    [60] => 2
    [Fastway] => 4
    [YUP] => 1
]

I don't know how efficient it is, but it seems to work. Needed this function in one of my scripts and thought I would share it.

array_count_values function does not work on multidimentional arrays.
If $score[][] is a bidimentional array, the command
"array_count_values [$score]" return the error message "Warning: Can only count STRING and INTEGER values!".
