FWIW, the rules for plist files are:
1. Read, via System Events, the entire contents of the file into a
record;
2. Modify the record using record concatenation;
3. Write, via System Events, the entire record back into the plist file.
When you use Property List Editor.app to inspect the plist file, do
not ever Dump to text. It's just confusing. Let System Events do that
for you.

Thanks Axel.
I wish to add a second entry to the plist (e.g. numberKey 6). All
my attempts can only override the existing one (in this case
numberKey 5):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://
www.apple.com/DTDs/PropertyList-1.0.dtd ">
<plist version="1.0">
<dict>
<key>numberKey</key>
<integer>5</integer>
</dict>
<dict>
<key>numberKey</key>
<integer>6</integer>
</dict>
</plist>
Hmm... this will be problematic.
In fact, a plist needs a root. With the above, you would have two
roots (moreover, those roots would be indistinguishable, as they
are unnamed and don't belong to an ordered set).
So, assuming you really want dictionaries, each holding a single
number, you would at least need something like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://
www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Some sub dict</key>
<dict>
<key>numberKey</key>
<integer>5</integer>
</dict>
<key>Another sub dict</key>
<dict>
<key>numberKey</key>
<string>6</string>
</dict>
</dict>
</plist>
Alternatively, you could consider an array for the root (an array
being an ordered set):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://
www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
<dict>
<key>numberKey</key>
<integer>5</integer>
</dict>
<dict>
<key>numberKey</key>
<integer>6</integer>
</dict>
</array>
</plist>
Perhaps could you a bit more precise about your needs, a plist of
cookies?
Do you have entire control over the format of that plist, or do you
have to comply with some requirements?
HTH,
Axel
