I have to second Don Cragun, your description is far from clear. Can I paraphrase it in a way that "check if field 1..13 are an index into array, on first match assign that element to field 5 and quit the check"?
If yes, I guess Don Cragun's proposal needs a small modification:
Code:
awk     '
FNR == NR       {array[$1] = $2
                 next
                }
                {for (i = 1; i <= 13; i++)
                        if($i in array) {$5 = array[$i]
                                         break
                                        }
                }
1
        ' file1 file2

What about field 5?

IGAWK(1)							 Utility Commands							  IGAWK(1)

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
