Actually, you don't need to sort at all Smilie

Code:
awk 'END {
  for (i = 1; ++i <= NR;)
    for (j = 1; ++j <= NF;)
      print m[i, j]  
  }
NR == 1 {
  split($0, c); next
  }
{
  for (i = 1; ++i <= NF;) 
    m[i, NR] = c[i - 1] OFS $1 OFS $i
  }'  matrice_prova.txt

In some awk implementations NR and NF may not be available in the END block,
in that case you'll need something like this:

Code:
awk 'END {
  for (i = 1; ++i <= nr;)
    for (j = 1; ++j <= nf;)
      print m[i, j]  
  }
NR == 1 {
  split($0, c); next
  }
{
  for (i = 1; ++i <= NF;) 
    m[i, NR] = c[i - 1] OFS $1 OFS $i
  nf = NF; nr = NR
  }'  matrice_prova.txt
