<script>
var tids = {
308: 1,
312: 1,
313: 1,
314: 1
};
</script>
results in "missing } in XML expression with an arrow pointing to the first colon in the JS error console. Isn't this a valid declaration?

First you should fix your <script> tag to
<script type="text/javascript">
Next, if you want to use numeric indexes, try to declare them as a string:
var tids = {
'308': 1,
'312': 1,
'313': 1,
'314': 1
};
Please note, however, that you will not be able to reference them in object notation (i.e. tids.308). You could simply use arrays instead of objects:

You could access it as tids['308'], though.

it was the type that was causing it.

Crockford says to not worry about the type attribute in your script tags. The OP's script tag is fine. javascript.crockford.com/script.html

Specifically, the script tag type defaults to text/javascript as part of HTML5. One might want to use the old tag for compatibility with older browsers. Or just decide they don't matter.
This isn't an associative array -- it's just a JS object. I believe you need to make the keys strings instead of numeric.
var tids = {
"308": 1,
"312": 1,
"313": 1,
"314": 1
};
More info on associative arrays vs. regular objects.

i guess that the key cannot start with a number. try;
<script>
var tids = {
n308: 1,
n312: 1,
n313: 1,
n314: 1
};
</script>

A key can start with a number.

I'm pretty sure the key can be a number, I think I've used it before.

I guess not. The key cannot start with a number at least it be declared like a string (in that case is not a number anymore)
I have tried in both IE and FF and the code is fine. It should be the error of other codes.
Please use Firefox Web Developer and Firebug to find the source of error.
<script type='text/javascript' language='javascript'>? Might help if your browser is confused for some reason...
