several plugins might add CSS using
$this->doc->inDocStylesArray[]

Lets imagine that plugin A is installed before you plugin and it adds

body#abc {... }

Then your plugin adds
@import url(....)

CSS, which has been added by your plugin doesn't work

the result is
<style...
body#abc {... }
@import url(...


@import-statement should *always be on the top of any other CSS -
just comments can be before it. If it is not on top, it is ignored.
I found this problem with erotea_date2cal, which used @import statement
- and didn't work because my plugin put new CSS *before* the @import 
statement.

Include instead using PHP, for example like this

$this->doc->inDocStylesArray[] = 
t3lib_div::getURL(t3lib_extMgm::extPath($_EXTKEY).'yourImportedCss.css');
