Perhaps mevans can make it possible in 1.8 to have the system,  but it would take plug-ins or command block to use it. A /skill command can change your skill, which can be used with the score and stats to make it work how it would want to.

for example:

/ execute testfor [examplestat=10] /skill[skilltype:1] set 10

/execute testfor score{examplescore=20} /skill[skilltype:2] set 30

are examples of ways /skill could be used in a command, but without a command or plug in it would not gain any value.
