Should I superscore my ACT if it doesn't affect the composite?

Some of the schools I’m applying to superscore the ACT.

June 2014:

C 34
M 35
E 35
S 34
R 32

February
C 32
S 35
M 34
E 29
R 30

I’m looking to replace the 34 in science from june with the 35 from february.

Will they see my other, older scores? Is it worth it?

Applying as a science major everywhere.

I wouldn’t, it has more chance to harm than help imo. They may just see regression or fluke.
