I guess the issue is in 'tarxz-name', defined within 'patch-and-repack':
(define (tarxz-name file-name)
;; Return a '.tar.xz' file name based on FILE-NAME.
(let ((base (if (numeric-extension? file-name)
original-file-name
(file-sans-extension file-name))))
(string-append base
(if (equal? (file-extension base) "tar")
".xz"
".tar.xz"))))
Unless the extension (everything after the last '.') of the original
file name is composed entirely of hexadecimal characters, it is removed.
In this case, I guess the extension is "3-checkout", so it's removed.
I'm reluctant to suggest a fix until I understand the rationale for this
behavior. It was added by Ludovic in February 2014, in commit
3ca00bb51e3ff906a700b6925e0ce81558c8c469.

packages: Support 'patches' and 'snippets' for sources that are directories.
* guix/packages.scm (patch-and-repack)[numeric-extension?, tarxz-name]:
New procedures.
[builder]: Adjust to deal with SOURCE when it's a directory.
<body>: Use 'tarxz-name'. Always add (guix build utils) to
IMPORTED-MODULES.
Do you remember why you decided to remove non-numeric extensions,
Ludovic?
Thanks,
Mark
