I guess you're looking for awk options / opportunities? There are several:
- just eliminate the last character: print substr ($5, 1, length($5)-1)
- eliminate the % character from $5: sub (/%/, "", $5), print $5
- or use a feature of awk when doing arithmetics: print $5+0
Once you're at it, and you're using awk anyhow, why not do all of it in awk?

mu-extract
MU-EXTRACT(1) General Commands Manual MU-EXTRACT(1)NAME
mu_extract - display and save message parts (attachments), and open them with other tools.
SYNOPSIS
mu extract [options] <file> mu extract [options] <file> <pattern>
DESCRIPTION
mu extact is the mu sub-command for extracting MIME-parts (e.g., attachments) from mail messages. It works on message files, and does not
require the message to be indexed in the database.
For attachments, the file name used when saving it, is the name of the attachment in the message. If there is no such name, or when saving
non-attachment MIME-parts, a name is derived from the message-id of the message.
If you specify a pattern (a case-insensitive regular expression) as the second argument, all attachments with filenames matching that pat-
tern will be extracted. The regular expressions are Perl-compatible (as per the PCRE-library).
Without any options, mu extract simply outputs the list of leaf MIME-parts in the message. Only 'leaf' MIME-parts (including RFC822 attach-
ments) are considered, multipart/* etc. are ignored.
OPTIONS -a, --save-attachments
save all MIME-parts that look like attachments.
--save-all
save all non-multipart MIME-parts.
--parts=<parts>
only consider the following numbered parts (comma-separated list).The numbers for the parts can be seen from running mu extract
without any options but only the message file.
--target-dir=<dir>
save the parts in the target directory rather than the current working directory.
--overwrite
overwrite existing files with the same name; by default overwriting is not allowed.
--play Try to 'play' (open) the attachment with the default
application for the particular file type. On MacOS, this uses the open program, on other platforms is uses xdg-open. You can choose
a different program by setting the MU_PLAY_PROGRAM environment variable.
EXAMPLES
To display information about all the MIME-parts in a message file:
$ mu extract msgfile
To extract MIME-part 3 and 4 from this message, overwriting existing files with the same name:
$ mu extract --parts=3,4 --overwrite msgfile
To extract all files ending in '.jpg' (case-insensitive):
$ mu extract msgfile '.*.jpg'
To extract an mp3-file, and play it in the the default mp3-playing application.
$ mu extract --play msgfile 'whoopsididitagain.mp3'
