Transform Series Of 7 Numbers In 0 - 4 Scores

I have a series of raws with 7 numbers in each raw; sums may vary a lot from raw to raw, and also differences between one number and the other in a same raw.

Now, i need to obtain a much simpler distribution of scores, so reducing differences.

I would need to transform all numbers into a 0-4 score distribution, according to differences between numbers in a same raw. It's like a kind of rank score.

I want to obtain in each raw:

- 1-2 numbers with score = 4 (if three or more numbers have similar values: no 4 scores)
- a maximum of 3-4 numbers with score 2-3 (according to differences between these numbers but also also according to the 4 scores already assigned)
- all other scores = 1 if the numbers are >0
- all other scores = 0 if the numbers are 0

example: |14|23|3|0|45|0|10| => |2|3|1|0|4|0|2|

Would it be possible to do with Excel?
