in reply to Choosing "best" - sorting hashes issue

You want a relational database. SQLite will do the trick, just fine. A table that looks something like: 
create table measurements (
    name varchar
   ,measurement int
   ,quality1 int
   ,quality2 int
   ,quality3 int
);

Obviously, you'd substitute quality1/quality2/etc. with the names of the qualities.

Then, if you want the five measurements for Name1 ordered by size, you use the following SQL statement: 

SELECT measurement, size
  FROM measurements
 WHERE name = 'Name1'
 ORDER BY size

Easy as pie.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
