I have two doubts about this wonderful piece:
1. What was the exact order of the numbers composed in 1927?
2. According my information the number 11, "Suur’ olet, Herra", was added for the edition of 1936. The original version of this work, "Den höga himlen" JS58a, composed in 1927, was scored for mixed choir a capella, and the version JS58b with the finnish text and arranged for male choir and organ (like opus 113 nº11). So, in that edition the arrangement wasn't by Sibelius, there is a mistake about the the date of this piece's addition, or Sibelius made the arrangement in 1936 or before this.
I'm sorry, my english isn't quite good! My blog about Sibelius in spanish:
