User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.13) Gecko/20110103 Fedora/3.6.13-1.fc14 Firefox/3.6.13

From the "execute a script block" section, step 5 indicates an asynchronous load event should be fired at local script elements when they complete. 

Otherwise, the script is internal; queue a task to fire a simple event named load at the script element.

http://www.whatwg.org/specs/web-apps/current-work/multipage/scripting-1.html#script

Gecko only fires the load event when a script contains a non-empty src attribute such as a URL or data-uri. 

Reproducible: Always

Steps to Reproduce:
1. Create script element
2. Assign text attribute
3. Assign onload handler
4. Attach script to DOM
Actual Results:  
Although the script runs, the onload event never fires. 

Expected Results:  
Per the specification, [If] the script is internal; queue a task to fire a simple event named load at the script element.

This is a relatively minor point and in many situations using a data-uri is an acceptable workaround; however, data-uri's cause the script to execute using different rules than those defined for local scripts (async execution, synchronous callback) which is not always acceptable.  

All versions of IE fire the onreadystatechange event on local script elements and IE9 fires the onload event at local scripts as well.  No other browsers exhibit similar behavior.
