I don't understand why you were using -F: in your awk scripts when there aren't any colons in your filenames. Here are a couple of ways to do it; one using ls, awk, rm, and bash; and the other one just using bash and rm. Both are presented in readable format and in 1-liner format:
Code:
#!/bin/bash
echo 'ls | awk | bash:'
ls | awk '
/[0-9][.]dok$/ {
	match($0, "[0-9]*[.]dok$")
	printf("echo mv \"%s\" \"%s%s.doc\"\n", $0, substr($0, 1, RSTART-1),
		substr($0, RSTART, length($0) - RSTART - 3) + 1)
}' | bash
printf '\n\nbash/ksh built-ins:\n'
for f in *[0-9].dok
do	b=${f%.dok}
	s=${b##*[!0-9]}
	b=${b%%[[0-9]*}
	echo mv "$f" "$b$((s+1)).doc"
done
printf '\n\nls | awk | bash 1-liner:\n'
ls|awk '/[0-9][.]dok$/{match($0,"[0-9]*[.]dok$");printf("echo mv \"%s\" \"%s%s.doc\"\n",$0,substr($0,1,RSTART-1),substr($0,RSTART,length($0)-RSTART-3)+1)}'|bash
printf '\n\nbash/ksh built-ins 1-liner:\n'
for f in *[0-9].dok;do	b=${f%.dok};s=${b##*[!0-9]};b=${b%%[[0-9]*};echo mv "$f" "$b$((s+1)).doc";done

If you find one that prints the mv commands you want to execute, remove the echo shown in red to actually rename the files.

The parameter expansion extracting the sequence number from the pathname works as long as there is only one string of digits in the filenames being processed (just before the .dok). The ERE in the awk script doesn't have this limitation, but your description didn't indicate that there could be multiple strings of digits; so I assume both methods do what you need.

Neither of these will do what you want if there are leading zeros on the digit strings in your filenames (such as value0012.dok).

OPTIONS

       The programs follow the usual GNU command line syntax, with long options starting with two dashes (`-') and short optoins starting with one
       dash.  A summary of options is included below.

       -B PIXMAP, --background=PIXMAP
	      Use the given pixmap as the clock background (size must be 64x64).

       -H COLOR, --hands-color=COLOR
	      Draw the hands (hour, minute and second) in the specified color.

       -S COLOR, --second-hand-color
	      Draw the second hand in the specified color

	      Show summary of options.

       -v, --version
	      Show version of program.
