Something like RUN+="eval bin/mount /dev/usbdrive"; /media/usbdrive/test.sh"?
Or put all commands in one script and run that:
RUN+="mount_and_test.sh"

Using the ; separator will not work. I tried adding eval, and still no
luck.
Putting the commands in one script is not feasible as I do not want the
script to reside on the machine, instead on the thumb drive. Does that
make sense?

Today you can have only one RUN key, it will change some day, but I
never got to finish the smarter rule parsing which will allow any
number of keys in a rule.
You need to do:
RUN+="/bin/sh -c '/program1; /program2'"
for now.

I have misunderstood either the poster's question or the paragraph in
"man udev" discussing the RUN key:
----excerpt----
RUN
Add a program to the list of programs to be executed for a specific
device. This can only be used for very short running tasks. Running an
event process for a long period of time may block all further events for
this or a dependent device. Long running tasks need to be immediately
detached from the event process itself.
----excerpt----
For example, this works:
SUBSYSTEM="*", RUN+="/root/udev-catch-remove"
ENV{DEVNAME}="/dev/foobar", RUN+="/path/to/prog"
Is this only working because the match keys are different?
Regards,
Richard

These are two rules with independent RUN keys, right?
The first on runs for _every_ event as the SUBSYSTEM match doesn't do
anything. The second may run when the env matches, but $DEVNAME is
usually not available at the time of rule processing. You can have any
number of rules with _one_ RUN key per rule and they will all be
executed.
The question was how to run two programs from a _single_ rule. The
obvious solution would be to specify two RUN keys, but that doesn't work
with todays in-memory rule presentation. It will change when I find the
time to work on that.
Thanks,
Kay

Would duplicate rules (with the same criteria) work? I.e., something
like:
BUS="scsi", ATTRS{model}="USB2FlashStorage", SYMLINK+="usbdrive",
RUN+="/bin/mount /dev/usbdrive"
BUS="scsi", ATTRS{model}="USB2FlashStorage", RUN+="/bin/sh
/media/usbdrive/test.sh"
(Where I've fixed the keys to match what udev >= 098 expects.)
Assuming these fire in the same order as they're in the rules file (and
multiple rules are allowed to have the same criteria), it should work
for what Adam needs (I think).

You could also use a GOTO/LABEL combination
BUS!="scsi", GOTO="usbdrive_end"
ATTRS{model}!="USB2FlashStorage", GOTO="usbdrive_end"
SYMLINK+="usbdrive"
RUN+="/bin/mount /dev/usbdrive"
RUN+="/bin/sh /media/usbdrive/test.sh"
LABEL="usbdrive_end"

That clarifies it, thanks.
Perhaps the man page could indicate:
RUN
If more than one program must be run for an event, a rule with one RUN
key must be written for each program. For example, to run three
programs, write three rules with identical match keys, each running one
of the three programs.
Does that decribe the situation accurately?
