Not sure of your intent to introduce dates or anything, but this is a bit of a workaround for what I think you're after. I've created a new sheet called "Lookup Sheet", and on that sheet is the following:
[TABLE="class: grid, width: 531"]

Back on sheet "1", I've done some rearranging and added some stuff:
[TABLE="class: grid, width: 741"]

The formula for the score in C5 is: =INDEX(INDIRECT("'"&INDEX('Lookup Sheet'!$E$4:$E$13,MATCH('1'!$E$1,'Lookup Sheet'!$C$4:$C$13,0)+MATCH('1'!$B$1,'Lookup Sheet'!$D$4:$D$8,1)-1)&"'!"&C3&":"&C3),MATCH(B5,INDIRECT("'"&INDEX('Lookup Sheet'!$E$4:$E$13,MATCH('1'!$E$1,'Lookup Sheet'!$C$4:$C$13,0)+MATCH('1'!$B$1,'Lookup Sheet'!$D$4:$D$8,1)-1)&"'!"&B3&":"&B3),0))
This can be copy and pasted into E5 and G5. I've added the Column values in row 3 based on where you've positioned your data on each of the tabs. This will need to be manually changed if you rearrange those other sheets (I could automate it, but your column headings don't match)
