You can avoid iterating the list by looking up a position:
property Codes : "x9420x94aex94d0x942fx942Cx9470x"
property Mnemonics : {"RCL", "ENM", "ReW", "EOC", "EDM", "RfW"}
set testCode to "9470"
my MnemonicOf(testCode)
on MnemonicOf(aCode)
set oldDelims to AppleScript's text item delimiters
set AppleScript's text item delimiters to {aCode}
set theOffset to length of item 1 of text items of Codes
set Mnem to (theOffset + 4) / 5
return item Mnem of Mnemonics
set AppleScript's text item delimiters to oldDelims
end MnemonicOf
