They are exported to commands even if the first letter is lowercase.

Let's see if I can explain this:

1. TextMate executes a command in the RSpec bundle
2. That command is implemented in bash, containing inline Ruby code. 
That is, Ruby code is piped to a file which is then executed
3. The Ruby code runs the tests

All variables (defined in Preferences → Variables), regardless of case, 
are available at step 2. But only environment variables starting with a 
capital letter are available in step 3.
