Problem with arrays in awk

Hello! I'm trying to make a script that will make a list of the files in a source tree and sort them by size. Problem is I've run into a weird problem.

Code:

print array[index]

will give me numbers like 160, 220, 444 that i don't even know where they come from, and

Code:

print array[index+1]

will give me the correct numbers !?? I'm puzzled. Thanks in advance!

Code:

du `find ./ -name *.c*` | awk '{ line[NR] = $0 
				 size[NR] = $1}
				    END { sort(line, size, NR)
					  for(i = 1; i < NR; i++) print line[i] }
				    function sort(A, S, Q,       Y, R, TEMP) {
					for(Y = 1; Y < Q; Y++){						
						for(R = 1; R < Q+1; R++) {
							if( S[Y] > S[Y+1] ) {
								print "TRUE: "S[Y] " is larger than " S[Y+1] "."
								print "S[" Y "] is " S[Y] " even though S[" (Y+1) "] is " S[Y+1] "."
								TEMP = S[Y]
								S[Y] = S[Y+1]
								S[Y+1]=TEMP
								TEMP = A[Y]
								A[Y] = A[Y+1]
								A[Y+1] = TEMP
							}
						}
					}
				    }' > sources

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
